"Updated gc packages that fix one security issue are now available for
Red Hat Satellite Proxy 5.6.

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.

Red Hat Satellite Proxy provides a package-caching mechanism that
reduces the bandwidth requirements for Red Hat Satellite and enables
custom package deployment. Red Hat Satellite Proxy customers are able
to cache RPM packages, such as are provided by Errata Updates from Red
Hat, or custom RPM packages generated by their organization, on an
internal, centrally-located server.

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 Red Hat Network Proxy 5.6 are advised to upgrade to these
updated packages, which contain a backported patch to correct this
issue. For this update to take effect, Red Hat Network Proxy must be
restarted. Refer to the Solution section for details."
