Descriptions

An issue was discovered in GNU libiberty, as distributed in GNU Binutils 2.32. simple_object_elf_match in simple-object-elf.c does not check for a zero shstrndx value, leading to an integer overflow and resultant heap-based buffer overflow.

Se ha descubierto una vulnerabilidad en GNU libiberty, tal y como se distribuye en GNU Binutils versión 2.32. simple_object_elf_match in simple-object-elf.c no comprueba un valor shstrndx de cero, lo que lleva a un desbordamiento de enteros y un desbordamiento de búfer basado en memoria dinámica.

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.
