Impact: Moderate
Public: 2012-06-05
Bugzilla: 828878: CVE-2012-2673 gc: malloc() and calloc() overflows

Details

The MITRE CVE dictionary describes this issue as:

Multiple integer overflows in the (1) GC_generic_malloc and (2) calloc funtions 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.
