Mandriva Linux Security Advisory 2012-158 - Multiple integer overflows in the calloc functions in malloc.c, and the GC_generic_malloc_ignore_off_page function in mallocx.c in Boehm-Demers-Weiser GC 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. The updated packages have been patched to correct this issue.
