Ubuntu 12.04 LTS : eglibc vulnerability (USN-3323-2) (Stack Clash)

High Nessus Plugin ID 101148


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


USN-3323-1 fixed a vulnerability in the GNU C Library. This update provides the corresponding update for Ubuntu 12.04 ESM.

It was discovered that the GNU C library did not properly handle memory when processing environment variables for setuid programs. A local attacker could use this in combination with another vulnerability to gain administrative 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 libc6 package. Note that the updated package may not be immediately available from the package repository or its mirrors.
