The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, is vulnerable to an invalid write of size 8 because of missing a malloc() return-value check to see if memory had actually been allocated in the _bfd_generic_get_section_contents function. This vulnerability causes programs that conduct an analysis of binary programs using the libbfd library, such as objcopy, to crash.
La librería Binary File Descriptor (BFD) (también conocida como libbfd), tal como se distribuye en GNU Binutils 2.28, es vulnerable a una escritura no válida de tamaño 8 provocada porque no se devuelve un valor que confirme la reserva de memoria en el caso de que la memoria se haya asignado en la función _bfd_generic_get_section_contents. Esta vulnerabilidad provoca la caída del servicio en programas que analizan binarios utilizando la librería libbfd, como objcopy.
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.
