========================================================================== Ubuntu Security Notice USN-1934-1 August 20, 2013
linux-ti-omap4 vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.04
Summary:
Several security issues were fixed in the kernel.
Software Description: - linux-ti-omap4: Linux kernel for OMAP4
Details:
Chanam Park reported a Null pointer flaw in the Linux kernel's Ceph client. A remote attacker could exploit this flaw to cause a denial of service (system crash). (CVE-2013-1059)
An information leak was discovered in the Linux kernel's fanotify interface. A local user could exploit this flaw to obtain sensitive information from kernel memory. (CVE-2013-2148)
Kees Cook discovered a format string vulnerability in the Linux kernel's disk block layer. A local user with administrator privileges could exploit this flaw to gain kernel privileges. (CVE-2013-2851)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 13.04: linux-image-3.5.0-231-omap4 3.5.0-231.47
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.
