An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. a heap-based buffer over-read in bfd_getl32 in libbfd.c allows an attacker to cause a denial of service through a crafted PE file. This vulnerability can be triggered by the executable objdump.
Se ha detectado una vulnerabilidad en la biblioteca Binary File Descriptor (BFD), también conocida como libbfd, tal y como se distribuye en GNU Binutils 2.31. Una sobrelectura de búfer basada en memoria dinámica (heap) en bfd_getl32 en libbfd.c permite que un atacante provoque una denegación de servicio (DoS) mediante un archivo PE manipulado. Esta vulnerabilidad puede ser desencadenada por el ejecutable objdump.
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.
