The bug was discovered 11/21/2012. The weakness was published 12/18/2012 by Alejandro Hernandez (nitr0us) with IOActive as Striking Back GDB and IDA debuggers through malformed ELF executables as confirmed blog post (Website) via IOActive. The advisory is shared for download at blog.ioactive.com. The public release happened without coordination with the vendor. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details and a public exploit are known. The problem exists when trying to open a malformed ELF that contains a file_entry.dir_index > 0 and char **include_dirs pointing to NULL.
