Red Hat: 2013:1500-01: gc: Moderate Advisory
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.
