 Mandriva Linux Security Advisory                         MDVSA-2012:158
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : gc
 Date    : October 3, 2012
 Affected: 2011., Enterprise Server 5.0
 _______________________________________________________________________

 Problem Description:

 A 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.
