Description Andrej Nemec 2017-11-29 04:36:12 EST

coffgen.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, does not validate the symbol count, which allows remote attackers to cause a denial of service (integer overflow and application crash, or excessive memory allocation) or possibly have unspecified other impact via a crafted PE file.
