The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, has an aout_link_add_symbols function in bfd/aoutx.h that is vulnerable to a heap-based buffer over-read (off-by-one) because of an incomplete check for invalid string offsets while loading symbols, leading to a GNU linker (ld) program crash.
"La librería Binary File Descriptor (BFD) (también conocida como libbfd), distribuida en GNU Binutils 2.28, tiene una función de aout_link_add_symbols en bfd / aoutx.h que es vulnerable a sobre lectura de búfer basado en memoria dinámica (oof-by-one) debido a una comprobación incompleta de los desplazamientos de cadena no válidos durante la carga de símbolos, lo que lleva a una caída del programa GNU linker (ld). "
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.
