## Description

Multiple integer overflows in the (1) \_objalloc\_alloc function in
objalloc.c and (2) objalloc\_alloc macro in include/objalloc.h in GNU
libiberty, as used by binutils 2.22, allow remote attackers to cause a
denial of service (crash) via vectors related to the "addition of
CHUNK\_HEADER\_SIZE to the length," which triggers a heap-based buffer
overflow.
