Detailed vulnerability description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

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.
