Description

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.

• CWE-190Integer Overflow or WraparoundThe product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
