Updated openswan packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the Red Hat Security Response Team.

Openswan is a free implementation of Internet Protocol Security (IPsec) and Internet Key Exchange (IKE). IPsec uses strong cryptography to provide both authentication and encryption services.
These services allow you to build secure tunnels through untrusted networks. Everything passing through the untrusted network is encrypted by the IPsec gateway machine, and decrypted by the gateway at the other end of the tunnel. The resulting tunnel is a virtual private network (VPN).

Multiple insufficient input validation flaws were found in the way Openswan's pluto IKE daemon processed some fields of X.509 certificates. A remote attacker could provide a specially crafted X.509 certificate that would crash the pluto daemon. (CVE-2009-2185)

All users of openswan are advised to upgrade to these updated packages, which contain a backported patch to correct these issues.
After installing this update, the ipsec service will be restarted automatically.

apr-util is a utility library used with the Apache Portable Runtime (APR). It aims to provide a free library of C data structures and routines. This library contains additional utility interfaces for APR;
including support for XML, LDAP, database interfaces, URI parsing, and more.

An off-by-one overflow flaw was found in the way apr-util processed a variable list of arguments. An attacker could provide a specially crafted string as input for the formatted output conversion routine, which could, on big-endian platforms, potentially lead to the disclosure of sensitive information or a denial of service (application crash). (CVE-2009-1956)

Note: The CVE-2009-1956 flaw only affects big-endian platforms, such as the IBM S/390 and PowerPC. It does not affect users using the apr-util package on little-endian platforms, due to their different organization of byte ordering used to represent particular data.

A denial of service flaw was found in the apr-util Extensible Markup Language (XML) parser. A remote attacker could create a specially crafted XML document that would cause excessive memory consumption when processed by the XML decoding engine. (CVE-2009-1955)

A heap-based underwrite flaw was found in the way apr-util created compiled forms of particular search patterns. An attacker could formulate a specially crafted search keyword, that would overwrite arbitrary heap memory locations when processed by the pattern preparation engine. (CVE-2009-0023)

All apr-util users should upgrade to these updated packages, which contain backported patches to correct these issues. Applications using the Apache Portable Runtime library, such as httpd, must be restarted for this update to take effect.

Updated kernel packages that fix several security issues and several bugs are now available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security fixes :

* several flaws were found in the way the Linux kernel CIFS implementation handles Unicode strings. CIFS clients convert Unicode strings sent by a server to their local character sets, and then write those strings into memory. If a malicious server sent a long enough string, it could write past the end of the target memory region and corrupt other memory areas, possibly leading to a denial of service or privilege escalation on the client mounting the CIFS share.
(CVE-2009-1439, CVE-2009-1633, Important)

* the Linux kernel Network File System daemon (nfsd) implementation did not drop the CAP_MKNOD capability when handling requests from local, unprivileged users. This flaw could possibly lead to an information leak or privilege escalation. (CVE-2009-1072, Moderate)

* Frank Filz reported the NFSv4 client was missing a file permission check for the execute bit in some situations. This could allow local, unprivileged users to run non-executable files on NFSv4 mounted file systems. (CVE-2009-1630, Moderate)

* a missing check was found in the hypervisor_callback() function in the Linux kernel provided by the kernel-xen package. This could cause a denial of service of a 32-bit guest if an application running in that guest accesses a certain memory location in the kernel.
(CVE-2009-1758, Moderate)

* a flaw was found in the AGPGART driver. The agp_generic_alloc_page() and agp_generic_alloc_pages() functions did not zero out the memory pages they allocate, which may later be available to user-space processes. This flaw could possibly lead to an information leak.
(CVE-2009-1192, Low)

Bug fixes :

* a race in the NFS client between destroying cached access rights and unmounting an NFS file system could have caused a system crash. 'Busy inodes' messages may have been logged. (BZ#498653)

* nanosleep() could sleep several milliseconds less than the specified time on Intel Itanium(r)-based systems. (BZ#500349)

* LEDs for disk drives in AHCI mode may have displayed a fault state when there were no faults. (BZ#500120)

* ptrace_do_wait() reported tasks were stopped each time the process doing the trace called wait(), instead of reporting it once.
(BZ#486945)

* epoll_wait() may have caused a system lockup and problems for applications. (BZ#497322)

* missing capabilities could possibly allow users with an fsuid other than 0 to perform actions on some file system types that would otherwise be prevented. (BZ#497271)

* on NFS mounted file systems, heavy write loads may have blocked nfs_getattr() for long periods, causing commands that use stat(2), such as ls, to hang. (BZ#486926)

* in rare circumstances, if an application performed multiple O_DIRECT reads per virtual memory page and also performed fork(2), the buffer storing the result of the I/O may have ended up with invalid data.
(BZ#486921)

* when using GFS2, gfs2_quotad may have entered an uninterpretable sleep state. (BZ#501742)

* with this update, get_random_int() is more random and no longer uses a common seed value, reducing the possibility of predicting the values returned. (BZ#499783)

* the '-fwrapv' flag was added to the gcc build options to prevent gcc from optimizing away wrapping. (BZ#501751)

* a kernel panic when enabling and disabling iSCSI paths. (BZ#502916)

* using the Broadcom NetXtreme BCM5704 network device with the tg3 driver caused high system load and very bad performance. (BZ#502837)

* '/proc/[pid]/maps' and '/proc/[pid]/smaps' can only be read by processes able to use the ptrace() call on a given process; however, certain information from '/proc/[pid]/stat' and '/proc/[pid]/wchan' could be used to reconstruct memory maps. (BZ#499546)

The kernel packages contain the Linux kernel, the core of any Linux operating system.

This update fixes the following security issues :

* a logic error was found in the do_setlk() function of the Linux kernel Network File System (NFS) implementation. If a signal interrupted a lock request, the local POSIX lock was incorrectly created. This could cause a denial of service on the NFS server if a file descriptor was closed before its corresponding lock request returned. (CVE-2008-4307, Important)

* a deficiency was found in the Linux kernel system call auditing implementation on 64-bit systems. This could allow a local, unprivileged user to circumvent a system call audit configuration, if that configuration filtered based on the 'syscall' number or arguments. (CVE-2009-0834, Important)

* the exit_notify() function in the Linux kernel did not properly reset the exit signal if a process executed a set user ID (setuid) application before exiting. This could allow a local, unprivileged user to elevate their privileges. (CVE-2009-1337, Important)

* a flaw was found in the ecryptfs_write_metadata_to_contents() function of the Linux kernel eCryptfs implementation. On systems with a 4096 byte page-size, this flaw may have caused 4096 bytes of uninitialized kernel memory to be written into the eCryptfs file headers, leading to an information leak. Note: Encrypted files created on systems running the vulnerable version of eCryptfs may contain leaked data in the eCryptfs file headers. This update does not remove any leaked data. Refer to the Knowledgebase article in the References section for further information. (CVE-2009-0787, Moderate)

* the Linux kernel implementation of the Network File System (NFS) did not properly initialize the file name limit in the nfs_server data structure. This flaw could possibly lead to a denial of service on a client mounting an NFS share. (CVE-2009-1336, Moderate)

This update also fixes the following bugs :

* the enic driver (Cisco 10G Ethernet) did not operate under virtualization. (BZ#472474)

* network interfaces using the IBM eHEA Ethernet device driver could not be successfully configured under low-memory conditions.

* NFS clients may have experienced deadlocks during unmount.
(BZ#488929)

* the ixgbe driver double counted the number of received bytes and packets. (BZ#489459)

* the Wacom Intuos3 Lens Cursor device did not work correctly with the Wacom Intuos3 12x12 tablet. (BZ#489460)

* on the Itanium(r) architecture, nanosleep() caused commands which used it, such as sleep and usleep, to sleep for one second more than expected. (BZ#490434)

* a panic and corruption of slab cache data structures occurred on 64-bit PowerPC systems when clvmd was running. (BZ#491677)

* the NONSTOP_TSC feature did not perform correctly on the Intel(r) microarchitecture (Nehalem) when running in 32-bit mode. (BZ#493356)

* keyboards may not have functioned on IBM eServer System p machines after a certain point during installation or afterward. (BZ#494293)

* using Device Mapper Multipathing with the qla2xxx driver resulted in frequent path failures. (BZ#495635)

* if the hypervisor was booted with the dom0_max_vcpus parameter set to less than the actual number of CPUs in the system, and the cpuspeed service was started, the hypervisor could crash. (BZ#495931)

* using Openswan to provide an IPsec virtual private network eventually resulted in a CPU soft lockup and a system crash.
(BZ#496044)

* it was possible for posix_locks_deadlock() to enter an infinite loop (under the BKL), causing a system hang. (BZ#496842)

A flaw was discovered in the way libpng handled PNG images containing 'unknown' chunks. If an application linked against libpng attempted to process a malformed, unknown chunk in a malicious PNG image, it could cause the application to crash. (CVE-2008-1382)

Users of libpng and libpng10 should upgrade to these updated packages, which contain backported patches to correct these issues. All running applications using libpng or libpng10 must be restarted for the update to take effect.

Updated kernel packages that resolve several security issues and fix various bugs are now available for Red Hat Enterprise Linux 4.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

This update addresses the following security issues :

* a buffer overflow was found in the Linux kernel Partial Reliable Stream Control Transmission Protocol (PR-SCTP) implementation. This could, potentially, lead to a denial of service if a Forward-TSN chunk is received with a large stream ID. (CVE-2009-0065, Important)

* a memory leak was found in keyctl handling. A local, unprivileged user could use this flaw to deplete kernel memory, eventually leading to a denial of service. (CVE-2009-0031, Important)

* a deficiency was found in the Remote BIOS Update (RBU) driver for Dell systems. This could allow a local, unprivileged user to cause a denial of service by reading zero bytes from the image_type or packet_size file in '/sys/devices/platform/dell_rbu/'. (CVE-2009-0322, Important)

* a deficiency was found in the libATA implementation. This could, potentially, lead to a denial of service. Note: by default, '/dev/sg*' devices are accessible only to the root user. (CVE-2008-5700, Low)

This update also fixes the following bugs :

* when the hypervisor changed a page table entry (pte) mapping from read-only to writable via a make_writable hypercall, accessing the changed page immediately following the change caused a spurious page fault. When trying to install a para-virtualized Red Hat Enterprise Linux 4 guest on a Red Hat Enterprise Linux 5.3 dom0 host, this fault crashed the installer with a kernel backtrace. With this update, the 'spurious' page fault is handled properly. (BZ#483748)

* net_rx_action could detect its cpu poll_list as non-empty, but have that same list reduced to empty by the poll_napi path. This resulted in garbage data being returned when net_rx_action calls list_entry, which subsequently resulted in several possible crash conditions. The race condition in the network code which caused this has been fixed.
(BZ#475970, BZ#479681 & BZ#480741)

* a misplaced memory barrier at unlock_buffer() could lead to a concurrent h_refcounter update which produced a reference counter leak and, later, a double free in ext3_xattr_release_block(). Consequent to the double free, ext3 reported an error

ext3_free_blocks_sb: bit already cleared for block [block number]

and mounted itself as read-only. With this update, the memory barrier is now placed before the buffer head lock bit, forcing the write order and preventing the double free. (BZ#476533)

* when the iptables module was unloaded, it was assumed the correct entry for removal had been found if 'wrapper->ops->pf' matched the value passed in by 'reg->pf'. If several ops ranges were registered against the same protocol family, however, (which was likely if you had both ip_conntrack and ip_contrack_* loaded) this assumption could lead to NULL list pointers and cause a kernel panic. With this update, 'wrapper->ops' is matched to pointer values 'reg', which ensures the correct entry is removed and results in no NULL list pointers.
(BZ#477147)

* when the pidmap page (used for tracking process ids, pids) incremented to an even page (ie the second, fourth, sixth, etc. pidmap page), the alloc_pidmap() routine skipped the page. This resulted in 'holes' in the allocated pids. For example, after pid 32767, you would expect 32768 to be allocated. If the page skipping behavior presented, however, the pid allocated after 32767 was 65536. With this update, alloc_pidmap() no longer skips alternate pidmap pages and allocated pid holes no longer occur. This fix also corrects an error which allowed pid_max to be set higher than the pid_max limit has been corrected. (BZ#479182)

All Red Hat Enterprise Linux 4 users should upgrade to these updated packages, which contain backported patches to resolve these issues.
The system must be rebooted for this update to take effect.

Security fixes :

* memory leaks were found on some error paths in the icmp_send() function in the Linux kernel. This could, potentially, cause the network connectivity to cease. (CVE-2009-0778, Important)

* Chris Evans reported a deficiency in the clone() system call when called with the CLONE_PARENT flag. This flaw permits the caller (the parent process) to indicate an arbitrary signal it wants to receive when its child process exits. This could lead to a denial of service of the parent process. (CVE-2009-0028, Moderate)

* an off-by-one underflow flaw was found in the eCryptfs subsystem.
This could potentially cause a local denial of service when the readlink() function returned an error. (CVE-2009-0269, Moderate)

* a deficiency was found in the Remote BIOS Update (RBU) driver for Dell systems. This could allow a local, unprivileged user to cause a denial of service by reading zero bytes from the image_type or packet_size files in '/sys/devices/platform/dell_rbu/'.
(CVE-2009-0322, Moderate)

* an inverted logic flaw was found in the SysKonnect FDDI PCI adapter driver, allowing driver statistics to be reset only when the CAP_NET_ADMIN capability was absent (local, unprivileged users could reset driver statistics). (CVE-2009-0675, Moderate)

* the sock_getsockopt() function in the Linux kernel did not properly initialize a data structure that can be directly returned to user-space when the getsockopt() function is called with SO_BSDCOMPAT optname set. This flaw could possibly lead to memory disclosure.
(CVE-2009-0676, Moderate)

* the ext2 and ext3 file system code failed to properly handle corrupted data structures, leading to a possible local denial of service when read or write operations were performed on a specially crafted file system. (CVE-2008-3528, Low)

* a deficiency was found in the libATA implementation. This could, potentially, lead to a local denial of service. Note: by default, the '/dev/sg*' devices are accessible only to the root user.
(CVE-2008-5700, Low)

Bug fixes :

* a bug in aic94xx may have caused kernel panics during boot on some systems with certain SATA disks. (BZ#485909)

* a word endianness problem in the qla2xx driver on PowerPC-based machines may have corrupted flash-based devices. (BZ#485908)

* a memory leak in pipe() may have caused a system deadlock. The workaround in Section 1.5, Known Issues, of the Red Hat Enterprise Linux 5.3 Release Notes Updates, which involved manually allocating extra file descriptors to processes calling do_pipe, is no longer necessary. (BZ#481576)

* CPU soft-lockups in the network rate estimator. (BZ#481746)

* bugs in the ixgbe driver caused it to function unreliably on some systems with 16 or more CPU cores. (BZ#483210)

* the iwl4965 driver may have caused a kernel panic. (BZ#483206)

* a bug caused NFS attributes to not update for some long-lived NFS mounted file systems. (BZ#483201)

* unmounting a GFS2 file system may have caused a panic. (BZ#485910)

* a bug in ptrace() may have caused a panic when single stepping a target. (BZ#487394)

* on some 64-bit systems, notsc was incorrectly set at boot, causing slow gettimeofday() calls. (BZ#488239)

* do_machine_check() cleared all Machine Check Exception (MCE) status registers, preventing the BIOS from using them to determine the cause of certain panics and errors. (BZ#490433)

* scaling problems caused performance problems for LAPI applications.
(BZ#489457)

* a panic may have occurred on systems using certain Intel WiFi Link 5000 products when booting with the RF Kill switch on. (BZ#489846)

* the TSC is invariant with C/P/T states, and always runs at constant frequency from now on. (BZ#489310)

Updated ntp packages to correct a security issue are now available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

The Network Time Protocol (NTP) is used to synchronize a computer's time with a referenced time source.

A flaw was discovered in the way the ntpd daemon checked the return value of the OpenSSL EVP_VerifyFinal function. On systems using NTPv4 authentication, this could lead to an incorrect verification of cryptographic signatures, allowing time-spoofing attacks.
(CVE-2009-0021)

Note: This issue only affects systems that have enabled NTP authentication. By default, NTP authentication is not enabled.

All ntp users are advised to upgrade to the updated packages, which contain a backported patch to resolve this issue. After installing the update, the ntpd daemon will restart automatically.

Updated kernel packages that resolve several security issues and fix various bugs are now available for Red Hat Enterprise Linux 4.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

This update addresses the following security issues :

* the sendmsg() function in the Linux kernel did not block during UNIX socket garbage collection. This could, potentially, lead to a local denial of service. (CVE-2008-5300, Important)

* when fput() was called to close a socket, the __scm_destroy() function in the Linux kernel could make indirect recursive calls to itself. This could, potentially, lead to a local denial of service.
(CVE-2008-5029, Important)

* a deficiency was found in the Linux kernel virtual file system (VFS) implementation. This could allow a local, unprivileged user to make a series of file creations within deleted directories, possibly causing a denial of service. (CVE-2008-3275, Moderate)

* a buffer underflow flaw was found in the Linux kernel IB700 SBC watchdog timer driver. This deficiency could lead to a possible information leak. By default, the '/dev/watchdog' device is accessible only to the root user. (CVE-2008-5702, Low)

* the hfs and hfsplus file systems code failed to properly handle corrupted data structures. This could, potentially, lead to a local denial of service. (CVE-2008-4933, CVE-2008-5025, Low)

* a flaw was found in the hfsplus file system implementation. This could, potentially, lead to a local denial of service when write operations were performed. (CVE-2008-4934, Low)

This update also fixes the following bugs :

* when running Red Hat Enterprise Linux 4.6 and 4.7 on some systems running Intel(r) CPUs, the cpuspeed daemon did not run, preventing the CPU speed from being changed, such as not being reduced to an idle state when not in use.

* mmap() could be used to gain access to beyond the first megabyte of RAM, due to insufficient checks in the Linux kernel code. Checks have been added to prevent this.

* attempting to turn keyboard LEDs on and off rapidly on keyboards with slow keyboard controllers, may have caused key presses to fail.

* after migrating a hypervisor guest, the MAC address table was not updated, causing packet loss and preventing network connections to the guest. Now, a gratuitous ARP request is sent after migration. This refreshes the ARP caches, minimizing network downtime.

* writing crash dumps with diskdump may have caused a kernel panic on Non-Uniform Memory Access (NUMA) systems with certain memory configurations.

* on big-endian systems, such as PowerPC, the getsockopt() function incorrectly returned 0 depending on the parameters passed to it when the time to live (TTL) value equaled 255, possibly causing memory corruption and application crashes.

* a problem in the kernel packages provided by the RHSA-2008:0508 advisory caused the Linux kernel's built-in memory copy procedure to return the wrong error code after recovering from a page fault on AMD64 and Intel 64 systems. This may have caused other Linux kernel functions to return wrong error codes.

* a divide-by-zero bug in the Linux kernel process scheduler, which may have caused kernel panics on certain systems, has been resolved.

* the netconsole kernel module caused the Linux kernel to hang when slave interfaces of bonded network interfaces were started, resulting in a system hang or kernel panic when restarting the network.

* the '/proc/xen/' directory existed even if systems were not running Red Hat Virtualization. This may have caused problems for third-party software that checks virtualization-ability based on the existence of '/proc/xen/'. Note: this update will remove the '/proc/xen/' directory on systems not running Red Hat Virtualization.

All Red Hat Enterprise Linux 4 users should upgrade to these updated packages, which contain backported patches to resolve these issues.

Updated avahi packages that fix a security issue are now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

Avahi is an implementation of the DNS Service Discovery and Multicast DNS specifications for Zeroconf Networking. It facilitates service discovery on a local network. Avahi and Avahi-aware applications allow you to plug your computer into a network and, with no configuration, view other people to chat with, see printers to print to, and find shared files on other computers.

Hugo Dias discovered a denial of service flaw in avahi-daemon. A remote attacker on the same local area network (LAN) could send a specially crafted mDNS (Multicast DNS) packet that would cause avahi-daemon to exit unexpectedly due to a failed assertion check.
(CVE-2008-5081)

All users are advised to upgrade to these updated packages, which contain a backported patch which resolves this issue. After installing the update, avahi-daemon will be restarted automatically.

Updated lcms packages that resolve several security issues are now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

Little Color Management System (LittleCMS, or simply 'lcms') is a small-footprint, speed-optimized open source color management engine.

Multiple insufficient input validation flaws were discovered in LittleCMS. An attacker could use these flaws to create a specially crafted image file which could cause an application using LittleCMS to crash, or, possibly, execute arbitrary code when opened.
(CVE-2008-5316, CVE-2008-5317)

Users of lcms should upgrade to these updated packages, which contain backported patches to correct these issues. All running applications using lcms library must be restarted for the update to take effect.

Updated dbus packages that fix a security issue are now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

D-Bus is a system for sending messages between applications. It is used for the system-wide message bus service and as a per-user-login-session messaging facility.

A denial-of-service flaw was discovered in the system for sending messages between applications. A local user could send a message with a malformed signature to the bus causing the bus (and, consequently, any process using libdbus to receive messages) to abort.
(CVE-2008-3834)

All users are advised to upgrade to these updated dbus packages, which contain backported patch which resolve this issue. For the update to take effect, all running instances of dbus-daemon and all running applications using libdbus library must be restarted, or the system rebooted.

Updated xen packages that resolve several security issues and a bug are now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

The xen packages contain the Xen tools and management daemons needed to manage virtual machines running on Red Hat Enterprise Linux.

Xen was found to allow unprivileged DomU domains to overwrite xenstore values which should only be changeable by the privileged Dom0 domain.
An attacker controlling a DomU domain could, potentially, use this flaw to kill arbitrary processes in Dom0 or trick a Dom0 user into accessing the text console of a different domain running on the same host. This update makes certain parts of the xenstore tree read-only to the unprivileged DomU domains. (CVE-2008-4405)

It was discovered that the qemu-dm.debug script created a temporary file in /tmp in an insecure way. A local attacker in Dom0 could, potentially, use this flaw to overwrite arbitrary files via a symlink attack. Note: This script is not needed in production deployments and therefore was removed and is not shipped with updated xen packages.
(CVE-2008-4993)

This update also fixes the following bug :

* xen calculates its running time by adding the hypervisor's up-time to the hypervisor's boot-time record. In live migrations of para-virtualized guests, however, the guest would over-write the new hypervisor's boot-time record with the boot-time of the previous hypervisor. This caused time-dependent processes on the guests to fail (for example, crond would fail to start cron jobs). With this update, the new hypervisor's boot-time record is no longer over-written during live migrations.

All xen users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues. The Xen host must be restarted for the update to take effect.

Updated thunderbird packages that fix several security issues are now available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the processing of malformed HTML mail content. An HTML mail message containing malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code as the user running Thunderbird. (CVE-2008-5500, CVE-2008-5501, CVE-2008-5502, CVE-2008-5511, CVE-2008-5512, CVE-2008-5513)

Several flaws were found in the way malformed content was processed.
An HTML mail message containing specially crafted content could potentially trick a Thunderbird user into surrendering sensitive information. (CVE-2008-5503, CVE-2008-5506, CVE-2008-5507)

Note: JavaScript support is disabled by default in Thunderbird; the above issues are not exploitable unless JavaScript is enabled.

A flaw was found in the way malformed URLs were processed by Thunderbird. This flaw could prevent various URL sanitization mechanisms from properly parsing a malicious URL. (CVE-2008-5508)

All Thunderbird users should upgrade to these updated packages, which resolve these issues. All running instances of Thunderbird must be restarted for the update to take effect.

An updated firefox package that fixes various security issues is now available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having critical security impact by the Red Hat Security Response Team.

Mozilla Firefox is an open source Web browser.

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code as the user running Firefox.
(CVE-2008-5500, CVE-2008-5501, CVE-2008-5502, CVE-2008-5511, CVE-2008-5512, CVE-2008-5513)

Several flaws were found in the way malformed content was processed. A website containing specially crafted content could potentially trick a Firefox user into surrendering sensitive information. (CVE-2008-5506, CVE-2008-5507)

A flaw was found in the way Firefox stored attributes in XML User Interface Language (XUL) elements. A website could use this flaw to track users across browser sessions, even if users did not allow the site to store cookies in the victim's browser. (CVE-2008-5505)

A flaw was found in the way malformed URLs were processed by Firefox.
This flaw could prevent various URL sanitization mechanisms from properly parsing a malicious URL. (CVE-2008-5508)

A flaw was found in Firefox's CSS parser. A malicious web page could inject NULL characters into a CSS input string, possibly bypassing an application's script sanitization routines. (CVE-2008-5510)

For technical details regarding these flaws, please see the Mozilla security advisories for Firefox 3.0.5. You can find a link to the Mozilla advisories in the References section.

Note: after the errata packages are installed, Firefox must be restarted for the update to take effect.

All firefox users should upgrade to these updated packages, which contain backported patches that correct these issues.

Updated cups packages that fix a security issue are now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

The Common UNIX(r) Printing System (CUPS) provides a portable printing layer for UNIX operating systems.

A NULL pointer dereference flaw was found in the way CUPS handled subscriptions for printing job completion notifications. A local user could use this flaw to crash the CUPS daemon by submitting a large number of printing jobs requiring mail notification on completion, leading to a denial of service. (CVE-2008-5183)

Users of cups should upgrade to these updated packages, which contain a backported patch to correct this issue.

Updated kernel packages that resolve several security issues and fix various bugs are now available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

* Olaf Kirch reported a flaw in the i915 kernel driver. This flaw could, potentially, lead to local privilege escalation. Note: the flaw only affects systems based on the Intel G33 Express Chipset and newer.
(CVE-2008-3831, Important)

* Miklos Szeredi reported a missing check for files opened with O_APPEND in the sys_splice(). This could allow a local, unprivileged user to bypass the append-only file restrictions. (CVE-2008-4554, Important)

* a deficiency was found in the Linux kernel Stream Control Transmission Protocol (SCTP) implementation. This could lead to a possible denial of service if one end of a SCTP connection did not support the AUTH extension. (CVE-2008-4576, Important)

In addition, these updated packages fix the following bugs :

* on Itanium(r) systems, when a multithreaded program was traced using the command 'strace -f', messages such as

PANIC: attached pid 10740 exited PANIC: handle_group_exit: 10740 leader 10721 ...

will be displayed, and after which the trace would stop. With these updated packages, 'strace -f' command no longer results in these error messages, and strace terminates normally after tracing all threads.

* on big-endian systems such as PowerPC, the getsockopt() function incorrectly returned 0 depending on the parameters passed to it when the time to live (TTL) value equaled 255.

* when using an NFSv4 file system, accessing the same file with two separate processes simultaneously resulted in the NFS client process becoming unresponsive.

* on AMD64 and Intel(r) 64 hypervisor-enabled systems, when a syscall correctly returned '-1' in code compiled on Red Hat Enterprise Linux 5, the same code, when run with the strace utility, would incorrectly return an invalid return value. This has been fixed: on AMD64 and Intel(r) 64 hypervisor-enabled systems, syscalls in compiled code return the same, correct values as syscalls run with strace.

* on the Itanium(r) architecture, fully-virtualized guest domains created using more than 64 GB of memory caused other guest domains not to receive interrupts. This caused soft lockups on other guests. All guest domains are now able to receive interrupts regardless of their allotted memory.

* when user-space used SIGIO notification, which was not disabled before closing a file descriptor and was then re-enabled in a different process, an attempt by the kernel to dereference a stale pointer led to a kernel crash. With this fix, such a situation no longer causes a kernel crash.

* modifications to certain pages made through a memory-mapped region could have been lost in cases when the NFS client needed to invalidate the page cache for that particular memory-mapped file.

* fully-virtualized Windows(r) guests became unresponsive due to the vIOSAPIC component being multiprocessor-unsafe. With this fix, vIOSAPIC is multiprocessor-safe and Windows guests do not become unresponsive.

* on certain systems, keyboard controllers could not withstand continuous requests to switch keyboard LEDs on or off. This resulted in some or all key presses not being registered by the system.

* on the Itanium(r) architecture, setting the 'vm.nr_hugepages' sysctl parameter caused a kernel stack overflow resulting in a kernel panic, and possibly stack corruption. With this fix, setting vm.nr_hugepages works correctly.

* hugepages allow the Linux kernel to utilize the multiple page size capabilities of modern hardware architectures. In certain configurations, systems with large amounts of memory could fail to allocate most of this memory for hugepages even if it was free. This could result, for example, in database restart failures.

Users should upgrade to these updated packages, which contain backported patches to correct these issues.

An updated enscript packages that fixes several security issues is now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

GNU enscript converts ASCII files to PostScript(R) language files and spools the generated output to a specified printer or saves it to a file. Enscript can be extended to handle different output media and includes options for customizing printouts.

Two buffer overflow flaws were found in GNU enscript. An attacker could craft an ASCII file in such a way that it could execute arbitrary commands if the file was opened with enscript with the 'special escapes' option (-e or --escapes) enabled. (CVE-2008-3863, CVE-2008-4306)

All users of enscript should upgrade to these updated packages, which contain backported patches to correct these issues.

Updated tog-pegasus packages that fix security issues are now available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The tog-pegasus packages provide OpenPegasus Web-Based Enterprise Management (WBEM) services. WBEM is a platform and resource independent Distributed Management Task Force (DMTF) standard that defines a common information model and communication protocol for monitoring and controlling resources.

Red Hat defines additional security enhancements for OpenGroup Pegasus WBEM services in addition to those defined by the upstream OpenGroup Pegasus release. For details regarding these enhancements, refer to the file 'README.RedHat.Security', included in the Red Hat tog-pegasus package.

After re-basing to version 2.7.0 of the OpenGroup Pegasus code, these additional security enhancements were no longer being applied. As a consequence, access to OpenPegasus WBEM services was not restricted to the dedicated users as described in README.RedHat.Security. An attacker able to authenticate using a valid user account could use this flaw to send requests to WBEM services. (CVE-2008-4313)

Note: default SELinux policy prevents tog-pegasus from modifying system files. This flaw's impact depends on whether or not tog-pegasus is confined by SELinux, and on any additional CMPI providers installed and enabled on a particular system.

Failed authentication attempts against the OpenPegasus CIM server were not logged to the system log as documented in README.RedHat.Security.
An attacker could use this flaw to perform password guessing attacks against a user account without leaving traces in the system log.
(CVE-2008-4315)

All tog-pegasus users are advised to upgrade to these updated packages, which contain patches to correct these issues.

Updated gnutls packages that fix a security issue are now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

The GnuTLS library provides support for cryptographic algorithms and for protocols such as Transport Layer Security (TLS).

Martin von Gagern discovered a flaw in the way GnuTLS verified certificate chains provided by a server. A malicious server could use this flaw to spoof its identity by tricking client applications using the GnuTLS library to trust invalid certificates. (CVE-2008-4989)

Users of GnuTLS are advised to upgrade to these updated packages, which contain a backported patch that corrects this issue.
