Subject: CVE-2006-6969 predictable session identifiers

Date: Thu, 4 Oct 2007 17:45:39 +0200

[Message part 1 (text/plain, inline)]

Package: jetty
Severity: grave
Tags: security

Hi,
the following CVE (Common Vulnerabilities & Exposures) id was
published for jetty.

CVE-2006-6969[0]:
| Jetty before 4.2.27, 5.1 before 5.1.12, 6.0 before 6.0.2, and 6.1
| before 6.1.0pre3 generates predictable session identifiers using
| java.util.random, which makes it easier for remote attackers to guess
| a session identifier through brute force attacks, bypass
| authentication requirements, and possibly conduct cross-site request
| forgery attacks.

If you fix this vulnerability please also include the CVE id
in your changelog entry.

This vulnerability has been verified in the Debian versions 
by the upstream.
I am currently waiting to get a patch for this.

For further information:
[0] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-6969

Kind regards
Nico
