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

high Nessus Plugin ID 101148
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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.
