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 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.

Details

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.

CVE-2012-2673 (GCVE-0-2012-2673)

Vulnerability from cvelistv5 – Published: 2012-07-25 19:00 – Updated: 2024-08-06 19:42

Summary

Multiple integer overflows in the (1) GC_generic_malloc and (2) calloc functions in malloc.c, and the (3) GC_generic_malloc_ignore_off_page function in mallocx.c in Boehm-Demers-Weiser GC (libgc) before 7.2 make it easier for context-dependent attackers to perform memory-related attacks such as buffer overflows via a large size value, which causes less memory to be allocated than expected.

Severity ?
