The print_gnu_property_note function in readelf.c in GNU Binutils 2.29.1 does not have integer-overflow protection on 32-bit platforms, which allows remote attackers to cause a denial of service (segmentation violation and application crash) or possibly have unspecified other impact via a crafted ELF file.
The 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.
