Description Dominic Hargreaves 2005-05-06 15:17:51 UTC
+++ This bug was initially created as a clone of Bug #157057 +++

Whilst playing with "random bitflipping" technology, an effective decompression
bomb attack against bzip2 was identified. bzip2 can be made to decompress
into a file indefinitely when it encounters a suitably corrupt bzip2 archive.

Demo bz2 archive:
http://scary.beasts.org/security/d5d5466da311d907/bomb.bz2

Fixed in 1.0.3.

No disclosure date yet.
