The aout_get_external_symbols function in aoutx.h in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, allows remote attackers to cause a denial of service (slurp_symtab invalid free and application crash) or possibly have unspecified other impact via a crafted ELF file.
La función aout_get_external_symbols en aoutx.h en la biblioteca Binary File Descriptor (BFD), conocida como libbfd, tal y como se distribuye en GNU Binutils 2.29.1 permite que atacantes remotos provoquen una denegación de servicio (liberación no válida de slurp_symtab y cierre inesperado de la aplicación) o, posiblemente, otro impacto sin especificar mediante un archivo ELF manipulado.
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.
