The get_count function in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.31, allows remote attackers to cause a denial of service (malloc called with the result of an integer-overflowing calculation) or possibly have unspecified other impact via a crafted string, as demonstrated by c++filt.
La función get_count en cplus-dem.c en GNU libiberty, tal y como se distribuye en GNU Binutils 2.31, permite que atacantes remotos provoquen una denegación de servicio (malloc llamado con el resultado de un cálculo que desborda un entero) o, posiblemente, otro tipo de impacto sin especificar mediante una cadena manipulada, tal y como queda demostrado por c++filt.
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.
