MGASA-2012-0249
Date: 	August 30th, 2012
Affected releases: 	1, 2


Description:
Updated gc packages fix security vulnerability:

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).


Updated Packages:
Mageia 1: lib(64)gc1-7.1-7.1.mga1
lib(64)gc-devel-7.1-7.1.mga1
lib(64)gc-static-devel-7.1-7.1.mga1

Mageia 2:
lib(64)gc1-7.2-0.alpha6.3.1.mga2
lib(64)gc-devel-7.2-0.alpha6.3.1.mga2
