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
(CVE-2012-2673).

The updated packages have been patched to correct this issue."
