Detailed vulnerability description
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The pe_bfd_read_buildid function in peicode.h in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, does not validate size and offset values in the data dictionary, which allows remote attackers to cause a denial of service (segmentation violation and application crash) or possibly have unspecified other impact via a crafted PE file.
