A GNU Denial Of Service Vulnerability
SecurityFocus has a vulnerability advisory about an issue with the GNU strings command and a potential Denial of Service attack. If a file contains certain character strings, the string command will crash due to a failure to properly handle unexpected user-supplied input.
The bugzilla entry 2584 authored by Jesus Olmos Gonzales, who discovered the issue, contains more information. It indicates the the issue actually lies within the bfd_hack_lookup() routine in the BFD library.
The results of initial testing done by several ISC Handlers made it appear that this was only affecting some Linux/Unix distributions and not others.
