Mandriva Linux Security Advisory : gc (MDVSA-2012:158)
Medium Nessus Plugin ID 62424
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionA security issue was identified and fixed in gc :
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.
SolutionUpdate the affected packages.
