Description Dominic Hargreaves 2005-05-06 15:14:49 UTC
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:

Fixed in 1.0.3.
