========================================================================== Ubuntu Security Notice USN-1487-1 June 29, 2012
linux vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10
Summary:
The system could be made to crash if it received specially crafted network traffic.
Software Description: - linux: Linux kernel
Details:
A flaw was discovered in the Linux kernel's NFSv4 (Network file system) handling of ACLs (access control lists). A remote NFS server (attacker) could cause a denial of service (OOPS).
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 11.10: linux-image-3.0.0-22-generic 3.0.0-22.36 linux-image-3.0.0-22-generic-pae 3.0.0-22.36 linux-image-3.0.0-22-omap 3.0.0-22.36 linux-image-3.0.0-22-powerpc 3.0.0-22.36 linux-image-3.0.0-22-powerpc-smp 3.0.0-22.36 linux-image-3.0.0-22-powerpc64-smp 3.0.0-22.36 linux-image-3.0.0-22-server 3.0.0-22.36 linux-image-3.0.0-22-virtual 3.0.0-22.36
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well.
