The remote OracleVM system is missing necessary patches to address critical security updates :

CVE-2008-4307 Race condition in the do_setlk function in fs/nfs/file.c in the Linux kernel before 2.6.26 allows local users to cause a denial of service (crash) via vectors resulting in an interrupted RPC call that leads to a stray FL_POSIX lock, related to improper handling of a race between fcntl and close in the EINTR case.

CVE-2009-1337 The exit_notify function in kernel/exit.c in the Linux kernel before 2.6.30-rc1 does not restrict exit signals when the CAP_KILL capability is held, which allows local users to send an arbitrary signal to a process by running a program that modifies the exit_signal field and then uses an exec system call to launch a setuid application.

CVE-2009-0834 The audit_syscall_entry function in the Linux kernel 2.6.28.7 and earlier on the x86_64 platform does not properly handle (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process making a 32-bit syscall, which allows local users to bypass certain syscall audit configurations via crafted syscalls, a related issue to CVE-2009-0342 and CVE-2009-0343.

CVE-2009-1336 fs/nfs/client.c in the Linux kernel before 2.6.23 does not properly initialize a certain structure member that stores the maximum NFS filename length, which allows local users to cause a denial of service (OOPS) via a long filename, related to the encode_lookup function.

  - CVE-2008-4307 -[nfs] remove bogus lock-if-signalled case     (Bryn M. Reeves) [456287 456288]

  - CVE-2009-1337 - [misc] exit_notify: kill the wrong     capable check 

  - CVE-2009-0834 - [ptrace] audit_syscall_entry to use     right syscall number (Jiri Pirko) [488001 488002]

  - CVE-2009-1336 - [nfs] v4: client crash on file lookup     with long names (Sachin S. Prabhu) [494078 493942]

These updated packages fix the following security issues :

  - 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)

  - 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)

  - a flaw was found in the Intel PRO/1000 network driver in     the Linux kernel. Frames with sizes near the MTU of an     interface may be split across multiple hardware receive     descriptors. Receipt of such a frame could leak through     a validation check, leading to a corruption of the     length check. A remote attacker could use this flaw to     send a specially crafted packet that would cause a     denial of service. (CVE-2009-1385, 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)

These updated packages also fix the following bugs :

  - '/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, making it possible to bypass     the Address Space Layout Randomization (ASLR) security     feature. This update addresses this issue. (BZ#499549)

  - in some situations, the link count was not decreased     when renaming unused files on NFS mounted file systems.
    This may have resulted in poor performance. With this     update, the link count is decreased in these situations,     the same as is done for other file operations, such as     unlink and rmdir. (BZ#501802)

  - tcp_ack() cleared the probes_out variable even if there     were outstanding packets. When low TCP keepalive     intervals were used, this bug may have caused problems,     such as connections terminating, when using remote tools     such as rsh and rlogin. (BZ#501754)

  - off-by-one errors in the time normalization code could     have caused clock_gettime() to return one billion     nanoseconds, rather than adding an extra second. This     bug could have caused the name service cache daemon     (nscd) to consume excessive CPU resources. (BZ#501800)

  - a system panic could occur when one thread read     '/proc/bus/input/devices' while another was removing a     device. With this update, a mutex has been added to     protect the input_dev_list and input_handler_list     variables, which resolves this issue. (BZ#501804)

  - using netdump may have caused a kernel deadlock on some     systems. (BZ#504565)

  - the file system mask, which lists capabilities for users     with a file system user ID (fsuid) of 0, was missing the     CAP_MKNOD and CAP_LINUX_IMMUTABLE capabilities. This     could, potentially, allow users with an fsuid other than     0 to perform actions on some file system types that     would otherwise be prevented. This update adds these     capabilities. (BZ#497269)

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.

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.
(BZ#487035)

* bonding with the 'arp_validate=3' option may have prevented fail overs. (BZ#488064)

* when running under virtualization, the acpi-cpufreq module wrote 'Domain attempted WRMSR' errors to the dmesg log. (BZ#488928)

* 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)

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.

  c. Third-party library update for ntp.
   The Network Time Protocol (NTP) is used to synchronize a computer's   time with a referenced time source.
   ESXi 3.5 and ESXi 4.0 have a ntp client that is affected by the   following security issue. Note that the same security issue is   present in the ESX Service Console as described in section d. of   this advisory.
   A buffer overflow flaw was discovered in the ntpd daemon's NTPv4   authentication code. If ntpd was configured to use public key   cryptography for NTP packet authentication, a remote attacker could   use this flaw to send a specially crafted request packet that could   crash ntpd or, potentially, execute arbitrary code with the   privileges of the 'ntp' user.
   The Common Vulnerabilities and Exposures Project (cve.mitre.org)   has assigned the name CVE-2009-1252 to this issue.
   The NTP security issue identified by CVE-2009-0159 is not relevant   for ESXi 3.5 and ESXi 4.0.
 d. Service Console update for ntp

  Service Console package ntp updated to version ntp-4.2.2pl-9el5_3.2    The Network Time Protocol (NTP) is used to synchronize a computer's   time with a referenced time source.
   The Service Console present in ESX is affected by the following   security issues.
   A buffer overflow flaw was discovered in the ntpd daemon's NTPv4   authentication code. If ntpd was configured to use public key   cryptography for NTP packet authentication, a remote attacker could   use this flaw to send a specially crafted request packet that could   crash ntpd or, potentially, execute arbitrary code with the   privileges of the 'ntp' user.
   NTP authentication is not enabled by default on the Service Console.
   The Common Vulnerabilities and Exposures Project (cve.mitre.org)   has assigned the name CVE-2009-1252 to this issue.
   A buffer overflow flaw was found in the ntpq diagnostic command. A   malicious, remote server could send a specially crafted reply to an   ntpq request that could crash ntpq or, potentially, execute   arbitrary code with the privileges of the user running the ntpq   command.
   The Common Vulnerabilities and Exposures Project (cve.mitre.org)   has assigned the name CVE-2009-0159 to this issue.

 f. Updated Service Console package python

  Service Console package Python update to version 2.4.3-24.el5.

  When the assert() system call was disabled, an input sanitization   flaw was revealed in the Python string object implementation that   led to a buffer overflow. The missing check for negative size values   meant the Python memory allocator could allocate less memory than   expected. This could result in arbitrary code execution with the   Python interpreter's privileges.

  Multiple buffer and integer overflow flaws were found in the Python   Unicode string processing and in the Python Unicode and string   object implementations. An attacker could use these flaws to cause   a denial of service.

  Multiple integer overflow flaws were found in the Python imageop   module. If a Python application used the imageop module to   process untrusted images, it could cause the application to   disclose sensitive information, crash or, potentially, execute   arbitrary code with the Python interpreter's privileges.

  Multiple integer underflow and overflow flaws were found in the   Python snprintf() wrapper implementation. An attacker could use   these flaws to cause a denial of service (memory corruption).

  Multiple integer overflow flaws were found in various Python   modules. An attacker could use these flaws to cause a denial of   service.

  An integer signedness error, leading to a buffer overflow, was   found in the Python zlib extension module. If a Python application   requested the negative byte count be flushed for a decompression   stream, it could cause the application to crash or, potentially,   execute arbitrary code with the Python interpreter's privileges.

  A flaw was discovered in the strxfrm() function of the Python   locale module. Strings generated by this function were not properly   NULL-terminated, which could possibly cause disclosure of data   stored in the memory of a Python application using this function.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the names CVE-2007-2052 CVE-2007-4965 CVE-2008-1721   CVE-2008-1887 CVE-2008-2315 CVE-2008-3142 CVE-2008-3143   CVE-2008-3144 CVE-2008-4864 CVE-2008-5031 to these issues.

 g. Updated Service Console package bind

  Service Console package bind updated to version 9.3.6-4.P1.el5

  The Berkeley Internet Name Domain (BIND) is an implementation of the   Domain Name System (DNS) protocols. BIND includes a DNS server   (named); a resolver library (routines for applications to use when   interfacing with DNS); and tools for verifying that the DNS server   is operating correctly.

  A flaw was found in the way BIND handles dynamic update message   packets containing the 'ANY' record type. A remote attacker could   use this flaw to send a specially crafted dynamic update packet   that could cause named to exit with an assertion failure.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the name CVE-2009-0696 to this issue.

 h. Updated Service Console package libxml2

  Service Console package libxml2 updated to version 2.6.26-2.1.2.8.

  libxml is a library for parsing and manipulating XML files. A   Document Type Definition (DTD) defines the legal syntax (and also   which elements can be used) for certain types of files, such as XML   files.

  A stack overflow flaw was found in the way libxml processes the   root XML document element definition in a DTD. A remote attacker   could provide a specially crafted XML file, which once opened by a   local, unsuspecting user, would lead to denial of service.

  Multiple use-after-free flaws were found in the way libxml parses   the Notation and Enumeration attribute types. A remote attacker   could provide a specially crafted XML file, which once opened by a   local, unsuspecting user, would lead to denial of service.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the names CVE-2009-2414 and CVE-2009-2416 to these   issues.

 i. Updated Service Console package curl

  Service Console package curl updated to version 7.15.5-2.1.el5_3.5

  A cURL is affected by the previously published 'null prefix attack',   caused by incorrect handling of NULL characters in X.509   certificates. If an attacker is able to get a carefully-crafted   certificate signed by a trusted Certificate Authority, the attacker   could use the certificate during a man-in-the-middle attack and   potentially confuse cURL into accepting it by mistake.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the name CVE-2009-2417 to this issue

 j. Updated Service Console package gnutls

  Service Console package gnutil updated to version 1.4.1-3.el5_3.5

  A flaw was discovered in the way GnuTLS handles NULL characters in   certain fields of X.509 certificates. If an attacker is able to get   a carefully-crafted certificate signed by a Certificate Authority   trusted by an application using GnuTLS, the attacker could use the   certificate during a man-in-the-middle attack and potentially   confuse the application into accepting it by mistake.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the name CVE-2009-2730 to this issue

From Red Hat Security Advisory 2009:0473 :

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.

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.
(BZ#487035)

* bonding with the 'arp_validate=3' option may have prevented fail overs. (BZ#488064)

* when running under virtualization, the acpi-cpufreq module wrote 'Domain attempted WRMSR' errors to the dmesg log. (BZ#488928)

* 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)

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.

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.

    (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)

Updated kernel packages that fix two security issues and two bugs are now available for Red Hat Enterprise Linux 4.7 Extended Update Support.

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 includes backported fixes for two approved security issues. These issues only affected users of Red Hat Enterprise Linux 4.7 Extended Update Support, as they have already been addressed for users of Red Hat Enterprise Linux 4 in the 4.8 update, RHSA-2009:1024.

* 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)

* the Linux kernel implementation of the Network File System (NFS) version 4 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 NFSv4 share. (CVE-2009-1336, Moderate)

This update fixes the following bugs :

* on IBM System z systems, if the cio driver was used for DASD devices, and the last path to a DASD device was varied off, it was still possible to attempt read and write operations to that device, resulting in errors. In this update, path verification is used in this situation, which resolves this issue. Also, a bug may have caused errors when subchannels were unregistered. (BZ#437486)

* a bug prevented the Broadcom NetXtreme II 57710 network device from working correctly on some Dell PowerEdge R805 systems. This device was correctly shown in 'lspci' output, but 'ifup' failed and an IP address was not assigned. In this update, the device works correctly on Dell PowerEdge R805 systems. (BZ#491752)

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

Igor Zhbanov discovered that NFS clients were able to create device nodes even when root_squash was enabled. An authenticated remote attacker could create device nodes with open permissions, leading to a loss of privacy or escalation of privileges. Only Ubuntu 8.10 and 9.04 were affected. (CVE-2009-1072)

Dan Carpenter discovered that SELinux did not correctly handle certain network checks when running with compat_net=1. A local attacker could exploit this to bypass network checks. Default Ubuntu installations do not enable SELinux, and only Ubuntu 8.10 and 9.04 were affected.
(CVE-2009-1184)

Shaohua Li discovered that memory was not correctly initialized in the AGP subsystem. A local attacker could potentially read kernel memory, leading to a loss of privacy. (CVE-2009-1192)

Benjamin Gilbert discovered that the VMX implementation of KVM did not correctly handle certain registers. An attacker in a guest VM could exploit this to cause a host system crash, leading to a denial of service. This only affected 32bit hosts. Ubuntu 6.06 was not affected.
(CVE-2009-1242)

Thomas Pollet discovered that the Amateur Radio X.25 Packet Layer Protocol did not correctly validate certain fields. A remote attacker could exploit this to read kernel memory, leading to a loss of privacy. (CVE-2009-1265)

Trond Myklebust discovered that NFS did not correctly handle certain long filenames. An authenticated remote attacker could exploit this to cause a system crash, leading to a denial of service. Only Ubuntu 6.06 was affected. (CVE-2009-1336)

Oleg Nesterov discovered that the kernel did not correctly handle CAP_KILL. A local user could exploit this to send signals to arbitrary processes, leading to a denial of service. (CVE-2009-1337)

Daniel Hokka Zakrisson discovered that signal handling was not correctly limited to process namespaces. A local user could bypass namespace restrictions, possibly leading to a denial of service. Only Ubuntu 8.04 was affected. (CVE-2009-1338)

Pavel Emelyanov discovered that network namespace support for IPv6 was not correctly handled. A remote attacker could send specially crafted IPv6 traffic that would cause a system crash, leading to a denial of service. Only Ubuntu 8.10 and 9.04 were affected. (CVE-2009-1360)

Neil Horman discovered that the e1000 network driver did not correctly validate certain fields. A remote attacker could send a specially crafted packet that would cause a system crash, leading to a denial of service. (CVE-2009-1385)

Pavan Naregundi discovered that CIFS did not correctly check lengths when handling certain mount requests. A remote attacker could send specially crafted traffic to cause a system crash, leading to a denial of service. (CVE-2009-1439)

Simon Vallet and Frank Filz discovered that execute permissions were not correctly handled by NFSv4. A local user could bypass permissions and run restricted programs, possibly leading to an escalation of privileges. (CVE-2009-1630)

Jeff Layton and Suresh Jayaraman discovered buffer overflows in the CIFS client code. A malicious remote server could exploit this to cause a system crash or execute arbitrary code as root.
(CVE-2009-1633)

Mikulas Patocka discovered that /proc/iomem was not correctly initialized on Sparc. A local attacker could use this file to crash the system, leading to a denial of service. Ubuntu 6.06 was not affected. (CVE-2009-1914)

Miklos Szeredi discovered that OCFS2 did not correctly handle certain splice operations. A local attacker could exploit this to cause a system hang, leading to a denial of service. Ubuntu 6.06 was not affected. (CVE-2009-1961).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
