Ubuntu 14.04 LTS / 16.04 LTS : GNU C Library vulnerability (USN-3323-1)

high Nessus Plugin ID 100921

Synopsis

The remote Ubuntu host is missing a security update.

Description

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.

Solution

Update the affected packages.
