Subject: segfaults in eigrp, hsrp, KeePass, skey, and SSH-ng
Hi all,
since the github issue tracker
https://github.com/magnumripper/JohnTheRipper/issues/ doesn't allow file
upload, I attach a fail.tgz with this contents:
$ tar tvzf fail.tgz
drwxrwxr-x fd/fd 0 2014-10-28 21:06 fail/
-rw-rw-r-- fd/fd 4355 2014-10-27 18:36 fail/fail_eigrp.pw
-rw-rw-r-- fd/fd 10034 2014-10-27 18:56 fail/fail_skey.pw
-rw-rw-r-- fd/fd 2720 2014-10-27 19:01 fail/fail_SSH-ng.pw
-rw-rw-r-- fd/fd 4167 2014-10-28 21:06 fail/fail_hsrp.pw
-rw-rw-r-- fd/fd 1444 2014-10-27 18:46 fail/fail_KeePass.pw
Each of these files contains a single test hash which causes the
corresponding format to segfault, so valid() needs to be improved.
These formats do have either a format2john.py or format2john converter,
which most likely create hashes that don't cause segfaults.
Nevertheless, john shouldn't segfault on these input files.
Just call john with the fail/fail_<format>.pw file name as the only
parameter to reproduce the segfault.
