Description Pedro Sampaio 2017-07-11 15:09:12 UTC 
The process_otr function in bfd/versados.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, does not validate a certain offset, which allows attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted binary file, as demonstrated by mishandling of this file during "objdump -D" execution.
