CVE-2014-8504

Desbordamiento de buffer basado en pila en la función srec_scan en bfd/srec.c en GNU binutils 2.24 y anteriores permite a atacantes remotos causar una denegación de servicio (caída) y posiblemente tener orto impacto no especificado a través de un fichero manipulado.

A stack-based buffer overflow flaw was found in the SREC parser of the libbfd library. A specially crafted file could cause an application using the libbfd library to crash or, potentially, execute arbitrary code with the privileges of the user running that application.

Multiple vulnerabilities have been found and corrected in binutils. Multiple integer overflows in the _objalloc_alloc function in objalloc.c and 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 via vectors related to the addition of CHUNK_HEADER_SIZE to the length, which triggers a heap-based buffer overflow. The srec_scan function in bfd/srec.c in libdbfd in GNU binutils before 2.25 allows remote attackers to cause a denial of service via a small S-record. Various other issues have also been addressed. The updated packages provide a solution for these security issues.
