Description Laura Pardo 2018-09-25 16:14:09 EDT

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.
