USN-1319-1: Linux kernel (OMAP4) vulnerabilities
Ubuntu Security Notice USN-1319-1
9th January, 2012
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.04
Several security issues were fixed in the kernel.
- linux-ti-omap4 - Linux kernel for OMAP4
Peter Huewe discovered an information leak in the handling of reading
security-related TPM data. A local, unprivileged user could read the
results of a previous TPM command. (CVE-2011-1162)
Clement Lecigne discovered a bug in the HFS filesystem. A local attacker
could exploit this to cause a kernel oops. (CVE-2011-2203)
A flaw was found in how the Linux kernel handles user-defined key types. An
unprivileged local user could exploit this to crash the system.
The problem can be corrected by updating your system to the following package version:
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.
