Subject: Summer bug cleaning - some Hash DoS stuff
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
So in the spirit of cleaning out the fridge of mystery condiments I'm
going through a bunch of old/lower severity bugs that have been
lurking in our BZ. To start with some Hash DoS related stuff from 2012:
https://bugzilla.redhat.com/show_bug.cgi?id=787103
CVE-2012-0880 xml: xerces-c hash table collisions CPU usage DoS
(oCERT-2011-003
https://bugzilla.redhat.com/show_bug.cgi?id=787104
CVE-2012-0881 xml: xerces-j2 hash table collisions CPU usage DoS
(oCERT-2011-003)
https://bugzilla.redhat.com/show_bug.cgi?id=787109
CVE-2012-0877 PyXML: hash table collisions CPU usage DoS (oCERT-2011-003)
Basically different code bases/etc, but all using poor hash
implementations.
