Ubuntu 8.04 LTS / 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : libgc vulnerability (USN-1546-1)

medium Nessus Plugin ID 61706

Language:

Synopsis

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

Description

It was discovered that multiple integer overflows existed in the malloc and calloc implementations in the Boehm-Demers-Weiser garbage collecting memory allocator (libgc). These could allow an attacker to cause a denial of service or possibly execute arbitrary code.

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 libgc1c2 package.
