Ubuntu 12.04 LTS : linux-lts-raring vulnerabilities (USN-2176-1)

High Nessus Plugin ID 73725


The remote Ubuntu host is missing a security-related patch.


A flaw was discovered in the Kernel Virtual Machine (KVM) subsystem of the Linux kernel. A guest OS user could exploit this flaw to execute arbitrary code on the host OS. (CVE-2014-0049)

Al Viro discovered an error in how CIFS in the Linux kernel handles uncached write operations. An unprivileged local user could exploit this flaw to cause a denial of service (system crash), obtain sensitive information from kernel memory, or possibly gain privileges.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected linux-image-3.8-generic package.
