Several security issues were fixed in the kernel.. =========================================================================Ubuntu Security Notice USN-1293-1 December 08, 2011 linux vulnerabilities ========================================================================= A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 10.10 Summary: Several security issues were fixed in the kernel. Software Description: - linux: Linux kernel Details: A bug was discovered in the XFS filesystem's handling of pathnames. A local attacker could exploit this to crash the system, leading to a denial of service, or gain root privileges. (CVE-2011-4077) Nick Bowler discovered the kernel GHASH message digest algorithm incorrectly handled error conditions. A local attacker could exploit this to cause a kernel oops. (CVE-2011-4081) A flaw was found in the Journaling Block Device (JBD). A local attacker able to mount ext3 or ext4 file systems could exploit this to crash the system, leading to a denial of service. (CVE-2011-4132) A bug was found in the way headroom check was performed in udp6_ufo_fragment() function. A remote attacker could use this flaw to crash the system. (CVE-2011-4326) Clement Lecigne discovered a bug in the HFS file system bounds checking. When a malformed HFS file system is mounted a local user could crash the system or gain root privileges. (CVE-2011-4330) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 10.10: linux-image-2.6.35-31-generic 2.6.35-31.63 linux-image-2.6.35-31-generic-pae 2.6.35-31.63 linux-image-2.6.35-31-omap 2.6.35-31.63 linux-image-2.6.35-31-powerpc 2.6.35-31.63 linux-image-2.6.35-31-powerpc-smp 2.6.35-31.63 linux-image-2.6.35-31-powerpc64-smp 2.6.35-31.63 linux-image-2.6.35-31-server 2.6.35-31.63 linux-image-2.6.35-31-versatile 2.6.35-31.63 linux-image-2.6.35-31-virtual 2.6.35-31.63 After astandard system update you need to reboot your computer to make all the necessary changes.

security advisoryRed Hatbug fixRed Hat: RHSA-2009:1672 Important: Kernel Exploit and DoS Fix
Updated kernel packages that fix multiple security issues and one bug are now available for Red Hat Enterprise Linux 5.2 Extended Update Support. This update has been rated as having important security impact by the Red Hat Security Response Team.. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ==================================================================== Red Hat Security Advisory Synopsis: Important: kernel security and bug fix update Advisory ID: RHSA-2009:1672-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2009:1672.html Issue date: 2009-12-15 CVE Names: CVE-2009-2695 CVE-2009-3547 ==================================================================== 1. Summary: Updated kernel packages that fix multiple security issues and one bug are now available for Red Hat Enterprise Linux 5.2 Extended Update Support. This update has been rated as having important security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux (v. 5.2.z server) - i386, ia64, noarch, ppc, s390x, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues: * a system with SELinux enforced was more permissive in allowing local users in the unconfined_t domain to map low memory areas even if the mmap_min_addr restriction was enabled. This could aid in the local exploitation of NULL pointer dereference bugs. (CVE-2009-2695, Important) * a NULL pointer dereference flaw was found in each of the following functions in the Linux kernel: pipe_read_open(), pipe_write_open(), and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe pointer could be released by other processes before it is used to update the pipe's reader and writer counters. This could lead to a local denial of service or privilege escalation. (CVE-2009-3547, Important) This update also fixes the followingbug: * a bug in the IPv6 implementation in the Linux kernel could have caused an unbalanced reference count. When using network bonding, this bug may have caused a hang when shutting the system down via "shutdown -h", or prevented the network service from being stopped via "service network stop". (BZ#538409) 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. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at 5. Bugs fixed (http://bugzilla.redhat.com/): 517830 - CVE-2009-2695 kernel: SELinux and mmap_min_addr 530490 - CVE-2009-3547 kernel: fs: pipe.c null pointer dereference 538409 - Unbalance reference count in ndisc_recv_ns [rhel-5.2.z] 6.

Summary: Updated kernel packages that fix multiple security issues and various bugs are now available for Red Hat Enterprise Linux 5.3 Extended Update Support. This update has been rated as having important security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux (v. 5.3.z server) - i386, ia64, noarch, ppc, s390x, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues: * a system with SELinux enforced was more permissive in allowing local users in the unconfined_t domain to map low memory areas even if the mmap_min_addr restriction was enabled. This could aid in the local exploitation of NULL pointer dereference bugs. (CVE-2009-2695, Important) * a NULL pointer dereference flaw was found in each of the following functions in the Linux kernel: pipe_read_open(), pipe_write_open(), and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe pointer could be released by other processes before it is used to update the pipe's reader and writer counters. This could lead to a local denial of service or privilege escalation. (CVE-2009-3547, Important) This update also fixes thefollowing bugs: * a caching bug in nfs_readdir() has been resolved. This may have caused parts of directory listings to become stale, as they came from cached data when they should not have, possibly causing NFS clients to see duplicate files or not see all files in a directory. (BZ#526959) * a bug prevented the pciehp driver from detecting PCI Express hot plug slots on some systems. (BZ#530381) * when a process attempted to read from a page that had first been accessed by writing to part of it (via write(2)), the NFS client needed to flush the modified portion of the page out to the server, and then read the entire page back in. This flush caused performance issues. (BZ#521243) * 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#525728) 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. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at 5. Bugs fixed (http://bugzilla.redhat.com/): 517830 - CVE-2009-2695 kernel: SELinux and mmap_min_addr 521243 - Read/Write NFS I/O performance degraded by FLUSH_STABLE page flushing [rhel-5.3.z] 525728 - cciss: spinlock deadlock causes NMI on HP systems [rhel-5.3.z] 526959 - [NetApp 5.5 bug] nfs_readdir() may fail to return all the files in the directory [rhel-5.3.z] 530381 - [5.3] PCIe hotplug slot detection failure [rhel-5.3.z] 530490 - CVE-2009-3547 kernel: fs: pipe.c null pointer dereference 6.
