========================================================================== Ubuntu Security Notice USN-2612-1 May 20, 2015
linux-ti-omap4 vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
Summary:
Several security issues were fixed in the kernel.
Software Description: - linux-ti-omap4: Linux kernel for OMAP4
Details:
A race condition between chown() and execve() was discovered in the Linux kernel. A local attacker could exploit this race by using chown on a setuid-user-binary to gain administrative privileges. (CVE-2015-3339)
Vincent Tondellier discovered an integer overflow in the Linux kernel's netfilter connection tracking accounting of loaded extensions. An attacker on the local area network (LAN) could potential exploit this flaw to cause a denial of service (system crash of targeted system). (CVE-2014-9715)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04 LTS: linux-image-3.2.0-1464-omap4 3.2.0-1464.84
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.
