libgc integer overflows
SecurityVulns ID:12549
Threat Level:
Description:Multiple integer overflows in malloc / calloc implementations.
Affected:LIBGC : libgc 7.1
CVE:CVE-2012-2673 (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.)
