Descriptions

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.

Varias vulnerabilidades de desbordamiento de enteros en la función _objalloc_alloc (1) en objalloc.c y (2) macro objalloc_alloc en include/objalloc.h en GNU libiberty, utilizada por binutils v2.22, permite a atacantes remotos provocar una denegación de servicio (caída) a través de vectores relacionada con la "adición de CHUNK_HEADER_SIZE a la longitud", lo que provoca un desbordamiento de búfer basado en heap
