Ubuntu alert USN-1567-1 (linux)
========================================================================== Ubuntu Security Notice USN-1567-1 September 14, 2012 linux vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 11.04 Summary: Several security issues were fixed in the kernel. Software Description: - linux: Linux kernel Details: A flaw was found in how the Linux kernel passed the replacement session keyring to a child process. An unprivileged local user could exploit this flaw to cause a denial of service (panic). (CVE-2012-2745) Ben Hutchings reported a flaw in the Linux kernel with some network drivers that support TSO (TCP segment offload). A local or peer user could exploit this flaw to to cause a denial of service. (CVE-2012-3412) Jay Fenlason and Doug Ledford discovered a bug in the Linux kernel implementation of RDS sockets. A local unprivileged user could potentially use this flaw to read privileged information from the kernel. (CVE-2012-3430) A flaw was discovered in the madvise feature of the Linux kernel's memory subsystem. An unprivileged local use could exploit the flaw to cause a denial of service (crash the system). (CVE-2012-3511) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.04: linux-image-2.6.38-16-generic 2.6.38-16.67 linux-image-2.6.38-16-generic-pae 2.6.38-16.67 linux-image-2.6.38-16-omap 2.6.38-16.67 linux-image-2.6.38-16-powerpc 2.6.38-16.67 linux-image-2.6.38-16-powerpc-smp 2.6.38-16.67 linux-image-2.6.38-16-powerpc64-smp 2.6.38-16.67 linux-image-2.6.38-16-server 2.6.38-16.67 linux-image-2.6.38-16-versatile 2.6.38-16.67 linux-image-2.6.38-16-virtual 2.6.38-16.67 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.
