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.
