Updated autofs packages that fix a security issue 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 autofs utility controls the operation of the automount daemon, which automatically mounts file systems when you use them, and unmounts them when you are not using them. This can include network file systems and CD-ROMs.

There was a security issue with the default configuration of autofs version 5, whereby the entry for the '-hosts' map did not specify the 'nodev' mount option. A local user with control of a remote NFS server could create special device files on the remote file system, that if mounted using the default '-hosts' map, could allow the user to access important system devices. (CVE-2007-6285)

This issue is similar to CVE-2007-5964, which fixed a missing 'nosuid' mount option in autofs. Both the 'nodev' and 'nosuid' options should be enabled to prevent a possible compromise of machine integrity.

Due to the fact that autofs always mounted '-hosts' map entries 'dev' by default, autofs has now been altered to always use the 'nodev' option when mounting from the default '-hosts' map. The 'dev' option must be explicitly given in the master map entry to revert to the old behavior. This change affects only the '-hosts' map which corresponds to the '/net' entry in the default configuration.

All autofs users are advised to upgrade to these updated packages, which resolve this issue.

Red Hat would like to thank Tim Baum for reporting this issue.

Updated libexif packages that fix 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.

The libexif packages contain the Exif library. Exif is an image file format specification that enables metadata tags to be added to existing JPEG, TIFF and RIFF files. The Exif library makes it possible to parse an Exif file and read this metadata.

An infinite recursion flaw was found in the way libexif parses Exif image tags. If a victim opens a carefully crafted Exif image file, it could cause the application linked against libexif to crash.
(CVE-2007-6351)

An integer overflow flaw was found in the way libexif parses Exif image tags. If a victim opens a carefully crafted Exif image file, it could cause the application linked against libexif to execute arbitrary code, or crash. (CVE-2007-6352)

Users of libexif are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.

Updated autofs packages are now available to fix a security flaw for Red Hat Enterprise Linux 5.

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

The autofs utility controls the operation of the automount daemon, which automatically mounts and unmounts file systems after a period of inactivity.

There was a security issue with the default installed configuration of autofs version 5 whereby the entry for the 'hosts' map did not specify the 'nosuid' mount option. A local user with control of a remote nfs server could create a setuid root executable within an exported filesystem on the remote nfs server that, if mounted using the default hosts map, would allow the user to gain root privileges.
(CVE-2007-5964)

Due to the fact that autofs always mounted hosts map entries suid by default, autofs has now been altered to always use the 'nosuid' option when mounting from the default hosts map. The 'suid' option must be explicitly given in the master map entry to revert to the old behavior. This change affects only the hosts map which corresponds to the /net entry in the default configuration.

Users are advised to upgrade to these updated autofs packages, which resolve this issue.

Red Hat would like to thank Josh Lange for reporting this issue.

Updated OpenSSL packages that correct several security issues are now available for Red Hat Enterprise 5.

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

OpenSSL is a toolkit that implements Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library. Datagram TLS (DTLS) is a protocol based on TLS that is capable of securing datagram transport (UDP for instance).

The OpenSSL security team discovered a flaw in DTLS support. An attacker could create a malicious client or server that could trigger a heap overflow. This is possibly exploitable to run arbitrary code, but it has not been verified (CVE-2007-4995). Note that this flaw only affects applications making use of DTLS. Red Hat does not ship any DTLS client or server applications in Red Hat Enterprise Linux.

A flaw was found in the SSL_get_shared_ciphers() utility function. An attacker could send a list of ciphers to an application that used this function and overrun a buffer with a single byte (CVE-2007-5135). Few applications make use of this vulnerable function and generally it is used only when applications are compiled for debugging.

A number of possible side-channel attacks were discovered affecting OpenSSL. A local attacker could possibly obtain RSA private keys being used on a system. In practice these attacks would be difficult to perform outside of a lab environment. This update contains backported patches designed to mitigate these issues. (CVE-2007-3108).

Users of OpenSSL should upgrade to these updated packages, which contain backported patches to resolve these issues.

Please note that the fix for the DTLS flaw involved an overhaul of the DTLS handshake processing which may introduce incompatibilities if a new client is used with an older server.

After installing this update, users are advised to either restart all services that use OpenSSL or restart their system.

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

This update fixes the following security issues :

* a flaw was found in the Realtek r8169 Ethernet driver in the Linux kernel. pci_unmap_single() presented a memory leak that could lead to IOMMU space exhaustion and a system crash. An attacker on the local network could trigger this flaw by using jumbo frames for large amounts of network traffic. (CVE-2009-3613, Important)

* NULL pointer dereference flaws were found in the r128 driver in the Linux kernel. Checks to test if the Concurrent Command Engine state was initialized were missing in private IOCTL functions. An attacker could use these flaws to cause a local denial of service or escalate their privileges. (CVE-2009-3620, Important)

* an information leak was found in the Linux kernel. On AMD64 systems, 32-bit processes could access and read certain 64-bit registers by temporarily switching themselves to 64-bit mode. (CVE-2009-2910, Moderate)

* the unix_stream_connect() function in the Linux kernel did not check if a UNIX domain socket was in the shutdown state. This could lead to a deadlock. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2009-3621, Moderate)

This update also fixes the following bugs :

* an iptables rule with the recent module and a hit count value greater than the ip_pkt_list_tot parameter (the default is 20), did not have any effect over packets, as the hit count could not be reached. (BZ#529306)

* in environments that use dual-controller storage devices with the cciss driver, Device-Mapper Multipath maps could not be detected and configured, due to the cciss driver not exporting the bus attribute via sysfs. This attribute is now exported. (BZ#529309)

* the kernel crashed with a divide error when a certain joystick was attached. (BZ#532027)

* a bug in the mptctl_do_mpt_command() function in the mpt driver may have resulted in crashes during boot on i386 systems with certain adapters using the mpt driver, and also running the hugemem kernel.
(BZ#533798)

* on certain hardware, the igb driver was unable to detect link statuses correctly. This may have caused problems for network bonding, such as failover not occurring. (BZ#534105)

* the RHSA-2009:1024 update introduced a regression. After updating to Red Hat Enterprise Linux 4.8 and rebooting, network links often failed to be brought up for interfaces using the forcedeth driver. 'no link during initialization' messages may have been logged. (BZ#534112)

* the RHSA-2009:1024 update introduced a second regression. On certain systems, PS/2 keyboards failed to work. (BZ#537344)

* a bug in checksum offload calculations could have crashed the bnx2x firmware when the iptable_nat module was loaded, causing network traffic to stop. (BZ#537013)

* a check has been added to the IPv4 code to make sure that the routing table data structure, rt, is not NULL, to help prevent future bugs in functions that call ip_append_data() from being exploitable.
(BZ#537016)

* possible kernel pointer dereferences on systems with several NFS mounts (a mixture of '-o lock' and '-o nolock'), which in rare cases may have caused a system crash, have been resolved. (BZ#537017)

Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

Updated samba packages that fix multiple 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.

Samba is a suite of programs used by machines to share files, printers, and other information.

A denial of service flaw was found in the Samba smbd daemon. An authenticated, remote user could send a specially crafted response that would cause an smbd child process to enter an infinite loop. An authenticated, remote user could use this flaw to exhaust system resources by opening multiple CIFS sessions. (CVE-2009-2906)

An uninitialized data access flaw was discovered in the smbd daemon when using the non-default 'dos filemode' configuration option in 'smb.conf'. An authenticated, remote user with write access to a file could possibly use this flaw to change an access control list for that file, even when such access should have been denied. (CVE-2009-1888)

A flaw was discovered in the way Samba handled users without a home directory set in the back-end password database (e.g. '/etc/passwd').
If a share for the home directory of such a user was created (e.g.
using the automated '[homes]' share), any user able to access that share could see the whole file system, possibly bypassing intended access restrictions. (CVE-2009-2813)

The mount.cifs program printed CIFS passwords as part of its debug output when running in verbose mode. When mount.cifs had the setuid bit set, a local, unprivileged user could use this flaw to disclose passwords from a file that would otherwise be inaccessible to that user. Note: mount.cifs from the samba packages distributed by Red Hat does not have the setuid bit set. This flaw only affected systems where the setuid bit was manually set by an administrator.
(CVE-2009-2948)

Users of Samba should upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, the smb service will be restarted automatically.

* the RHSA-2007:0354 update added code to escape input passed to scripts that are run by Samba. This code was missing 'c' from the list of valid characters, causing it to be escaped. With this update, the previous patch has been updated to include 'c' in the list of valid characters. (BZ#242754)

Users of Samba should upgrade to these updated packages, which contain a backported patch to correct this issue. After installing this update, the smb service will be restarted automatically.

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

This update has been rated as having moderate 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 fixes the following security issues :

* multiple, missing initialization flaws were found in the Linux kernel. Padding data in several core network structures was not initialized properly before being sent to user-space. These flaws could lead to information leaks. (CVE-2005-4881, CVE-2009-3228, Moderate)

This update also fixes the following bugs :

* a packet duplication issue was fixed via the RHSA-2008:0665 update;
however, the fix introduced a problem for systems using network bonding: Backup slaves were unable to receive ARP packets. When using network bonding in the 'active-backup' mode and with the 'arp_validate=3' option, the bonding driver considered such backup slaves as being down (since they were not receiving ARP packets), preventing successful failover to these devices. (BZ#519384)

* due to insufficient memory barriers in the network code, a process sleeping in select() may have missed notifications about new data. In rare cases, this bug may have caused a process to sleep forever.
(BZ#519386)

* the driver version number in the ata_piix driver was not changed between Red Hat Enterprise Linux 4.7 and Red Hat Enterprise Linux 4.8, even though changes had been made between these releases. This could have prevented the driver from loading on systems that check driver versions, as this driver appeared older than it was. (BZ#519389)

* a bug in nlm_lookup_host() could have led to un-reclaimed locks on file systems, resulting in the umount command failing. This bug could have also prevented NFS services from being relocated correctly in clustered environments. (BZ#519656)

* the data buffer ethtool_get_strings() allocated, for the igb driver, was smaller than the amount of data that was copied in igb_get_strings(), because of a miscalculation in IGB_QUEUE_STATS_LEN, resulting in memory corruption. This bug could have led to a kernel panic. (BZ#522738)

* in some situations, write operations to a TTY device were blocked even when the O_NONBLOCK flag was used. A reported case of this issue occurred when a single TTY device was opened by two users (one using blocking mode, and the other using non-blocking mode). (BZ#523930)

* a deadlock was found in the cciss driver. In rare cases, this caused an NMI lockup during boot. Messages such as 'cciss: controller cciss[x] failed, stopping.' and 'cciss[x]: controller not responding.' may have been displayed on the console. (BZ#525725)

* on 64-bit PowerPC systems, a rollover bug in the ibmveth driver could have caused a kernel panic. In a reported case, this panic occurred on a system with a large uptime and under heavy network load.
(BZ#527225)

Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.
