Description Sam Fowler 2018-02-19 04:37:39 UTC 
In GNU Binutils through version 2.30, the coff_pointerize_aux function in coffgen.c in the Binary File Descriptor (BFD) library (aka libbfd), an index is not properly validated, allowing an attacker to cause a denial of service via a crash (segmentation fault) when parsing a file with a crafted COFF file.
