The display_debug_frames function in dwarf.c in GNU Binutils 2.29.1 allows remote attackers to cause a denial of service (integer overflow and heap-based buffer over-read, and application crash) or possibly have unspecified other impact via a crafted ELF file, related to print_debug_frame.
La función display_debug_frames en dwarf.c en GNU Binutils 2.29.1 permite que atacantes remotos provoquen una denegación de servicio (desbordamiento de enteros, sobrelectura de búfer basada en memoria dinámica o heap y cierre inesperado de la aplicación) o, probablemente, provocar cualquier otro tipo de impacto mediante un archivo ELF modificado, relacionado con print_debug_frame.
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.
