Descriptions
An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. There is a heap-based buffer over-read in _bfd_doprnt in bfd.c because elf_object_p in elfcode.h mishandles an e_shstrndx section of type SHT_GROUP by omitting a trailing '\0' character.
Fue encontrado un problema en la biblioteca Binary File Descriptor (BFD), también conocida como libbfd, tal y como se distribuye en GNU Binutils 2.32. Se ha descubierto un problema en las versiones 0.7 y 0.7.1645 de GNU LibreDWG. Hay una sobrelectura de búfer basada en memoria dinámica (heap) en _bfd_doprnt in bfd.c porque elf_object_p in elfcode.h mishandles an e_shstrndx section of type SHT_GROUP mediante la omisión de un carácter \0' final.
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.
