DESCRIPTION:
Michael Krax has reported a vulnerability in Bugzilla, which can be
exploited by malicious people to conduct cross-site scripting
attacks.

Input passed in HTTP requests is not properly sanitised before being
returned to users in error messages when an internal error is
encountered. This can be exploited to execute arbitrary HTML and
script code in a user's browser session in context of a vulnerable
site.

SOLUTION:
Fixes are reportedly available in the CVS repository.
