Description Josh Bressers 2005-05-12 16:11:51 UTC
Chris Evans discovered a denial of service issue in bzip2.

http://scary.beasts.org/security/d5d5466da311d907/CESA-2005-002.txt

This issue has been fixed in bzip2 1.0.3, but it's not well known yet.  I'm
going to keep this bug private until chris makes his advisory public.

This issue also affects RHEL2.1 and RHEL3
