Vulnerability from csaf_redhat - Published: 2013-11-04 18:10 - Updated: 2026-06-25 10:40Summary
Red Hat Security Advisory: gc security update
Severity
Moderate
Notes
Topic: 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.
Details: 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.

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.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
