1. Impact
A vulnerability in the Sun Java Enterprise System (JES) may allow
remote unprivileged users to construct certificates with forged
signatures that go undetected and are accepted as valid signatures.
These unprivileged users may be able to operate servers that falsely
pose as other servers or generate forged signatures on emails and
software downloads without detection.
This issue is also described in the following documents:
CERT VU#845620 at http://www.kb.cert.org/vuls/id/845620

http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4339
Note: The issue described in this Sun Alert is specific to Sun Java
Enterprise System (JES). Multiple Sun products are affected by this
issue; for more details please see Sun Alert 102648 at
http://sunsolve.sun.com/search/document.do?assetkey=1-26-102648-1

Linux) without patch 121656-10
HP-UX Platform
* Sun Java Enterprise System 2005Q1 and 2005Q4 (for HP-UX) without
patch 124379-01
Notes:
1. Sun Java Enterprise System is not available for Solaris 8 on the
x86 platform.
2. This vulnerability affects all NSS-based SSL clients and S/MIME
email programs which use NSS versions below 3.11.3.
3. This vulnerability also affects products that verify signatures on
downloaded files.
Among NSS-based server products, this vulnerability only affects those
that:
A) act as SSL clients (including LDAPS clients), or
B) request and accept certificates from remote SSL clients.
This vulnerability stems from the code that verifies RSA signatures of
the kind commonly used on X.509 certificates known as "PKCS#1" version
1.5 RSA signatures.
To determine if the NSS packages are installed on a system, the
following command can be run:
% pkginfo SUNWtls
To determine the version of NSS on a system, the following command can
be run:
% pkgparam SUNWtls SUNW_PRODVERS
3. Symptoms
There are no predictable symptoms that would indicate the described
issue has occurred.
4. Relief/Workaround
There is no workaround for this issue. Please see the Resolution
section below.
5. Resolution
