========================================================================== Ubuntu Security Notice USN-2115-1 February 18, 2014
linux-ti-omap4 vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.10
Summary:
Several security issues were fixed in the kernel.
Software Description: - linux-ti-omap4: Linux kernel for OMAP4
Details:
Vasily Kulikov reported a flaw in the Linux kernel's implementation of ptrace. An unprivileged local user could exploit this flaw to obtain sensitive information from kernel memory. (CVE-2013-2929)
A flaw in the handling of memory regions of the kernel virtual machine (KVM) subsystem was discovered. A local user with the ability to assign a device could exploit this flaw to cause a denial of service (memory consumption). (CVE-2013-4592)
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 and Fabian Yamaguchi reported a flaw in the driver for Adaptec AACRAID scsi raid devices in the Linux kernel. A local user could use this flaw to cause a denial of service or possibly other unspecified impact. (CVE-2013-6380)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.10: linux-image-3.5.0-238-omap4 3.5.0-238.54
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.
