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.

Comment 1 Josh Bressers 2005-05-12 16:13:20 UTC
This issue also affects RHEL2.1 and RHEL3
