A security issue affects these releases of Ubuntu and its derivatives:
Several security issues were fixed in the kernel.
Stephan Mueller reported an error in the Linux kernel’s ansi cprng random number generator. This flaw makes it easier for a local attacker to break cryptographic protections. (CVE-2013-4345)
A flaw was discovered in the Linux kernel’s IP Virtual Server (IP_VS) support. A local user with the CAP_NET_ADMIN capability could exploit this flaw to gain additional administrative privileges. (CVE-2013-4588)
Nico Golde and Fabian Yamaguchi reported a flaw in the Linux kernel’s debugfs filesystem. An administrative local user could exploit this flaw to cause a denial of service (OOPS). (CVE-2013-6378)
Nico Golde reported a flaw in the Linux kernel’s userspace IO (uio) driver. A local user could exploit this flaw to cause a denial of service (memory corruption) or possibly gain privileges. (CVE-2013-6763)
The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
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.
