Vulnerability from csaf_redhat - Published: 2014-02-10 17:29 - Updated: 2026-01-28 22:35
Summary
Red Hat Security Advisory: gc security update

Notes

Topic
Updated gc packages that fix one security issue are now available for Red Hat Satellite 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.
Details
Red Hat Satellite is a systems management tool for Linux-based infrastructures. It allows for provisioning, remote management and monitoring of multiple Linux deployments with a single, centralized tool. 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 Satellite 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 Satellite must be restarted. Refer to the Solution section for details.
