The pe_bfd_read_buildid function in peicode.h in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, does not validate size and offset values in the data dictionary, which allows remote attackers to cause a denial of service (segmentation violation and application crash) or possibly have unspecified other impact via a crafted PE file.
La función pe_bfd_read_buildid en peicode.h en la biblioteca Binary File Descriptor (BFD), conocida como libbfd, tal y como se distribuye en GNU Binutils 2.29.1 no valida los valores de tamaño y desplazamiento en el diccionario de datos, lo que permite que atacantes remotos provoquen una denegación de servicio (violación de segmentación y cierre inesperado de la aplicación) o, posiblemente, otro impacto sin especificar mediante un archivo PE manipulado.
USN-4336-1 fixed several vulnerabilities in GNU binutils. This update provides the corresponding update for Ubuntu 16.04 ESM. It was discovered that GNU binutils contained a large number of security issues. If a user or automated system were tricked into processing a specially-crafted file, a remote attacker could cause GNU binutils to crash, resulting in a denial of service, or possibly execute arbitrary code. Various other issues were also addressed.
