Description Lubomir Kundrak 2006-12-04 14:18:59 UTC

+++ This bug was initially created as a clone of Bug #218287 +++

Description of problem:

JVN#84798830 described a problem in cgi.rb, which results in infinite loop after
certain HTTP request. While the original advisory is in Japan, you might want to
translate it with Babelfish. Anyways, it doesn't contain any useful information.
The upstream corrected the problem immediately in CVS and even released a new
package with patchlevel of 2.

Version-Release number of selected component (if applicable):

All supported versions (RHEL 2.1 to 5, and both FC 5 and FC 6) seem to contain
the vulnerable code.

How reproducible:

No reproducer.
