red hat
Calendar Grey November 4, 2013
Dist Redhat Esm H88
The recent gc package updates for Red Hat Enterprise Linux 6 address one significant security vulnerability concerning memory management.
Updated gc packages that fix one security issue are now available for Red Hat Enterprise Linux 6

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

Summary

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.
