Descriptions

finish_stab in stabs.c in GNU Binutils 2.30 allows attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact, as demonstrated by an out-of-bounds write of 8 bytes. This can occur during execution of objdump.

finish_stab en stabs.c en GNU Binutils 2.30 permite que los atacantes provoquen una denegación de servicio (desbordamiento de búfer basado en memoria dinámica o heap) u otro tipo de impacto sin especificar. Esto queda demostrado con una escritura fuera de límites de 8 bytes. Esto puede ocurrir durante la ejecución de objdump.

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.
