Title:
ReiserFS filename hash collision causing DoS
Status in linux package in Ubuntu:
Invalid
Bug description:
Binary package hint: linux-image-2.6-k7
If you create files in a directory on reiserfs, it is possible to
saturate the hash table such that new files with particular filenames
cannot be created.
This bug actually dates back to about 2004, but is still extant:
http://marc.info/?l=reiserfs&m=110434667931228&w=2
(The above post contains a script that demonstrates the problem which
works on my Feisty system.)
This theoretically allows attackers to DoS temporary directories, etc,
but does not appear to cause actual data loss. According to the
originally post, this has also actually been seen in real life,
although accidentally, not part of an attack.
It surprises me slightly that this bug has been around for so long,
given the potential seriousness...
