The getvalue function in tekhex.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, allows remote attackers to cause a denial of service (stack-based buffer over-read and application crash) via a crafted tekhex file, as demonstrated by mishandling within the nm program.
La función getvalue en el archivo teckhex.c en la librería Binary File Descriptor (BFD), distribuida en GNU Binutils 2.28, permite a un atacante remoto causar una denegación de servicio (buffer overread en la pila -stack- y caída de la aplicación) mediante la manipulación de archivo tekhex, como se demuestra por la mala gestión dentro del programa nm.
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.
