Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated gc packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

gc is a Boehm-Demers-Weiser conservative garbage collector for C and C++.

It was discovered that gc's implementation of the malloc() and calloc() routines did not properly perform parameter sanitization when allocating memory. If an application using gc did not implement application-level validity checks for the malloc() and calloc() routines, a remote attacker could provide specially crafted application-specific input, which, when processed by the application, could lead to an application crash or, potentially, arbitrary code execution with the privileges of the user running the application.
(CVE-2012-2673)

Users of gc are advised to upgrade to these updated packages, which contain backported patches to correct this issue. Applications using gc must be restarted for the update to take effect.

Solution

Update the affected gc, gc-debuginfo and / or gc-devel packages.
