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.
