New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote openSUSE host is missing a security update.
Descriptionseamonkey was updated to version 1.1.18, fixing various security issues :
MFSA 2009-43 / CVE-2009-2404 Moxie Marlinspike reported a heap overflow vulnerability in the code that handles regular expressions in certificate names. This vulnerability could be used to compromise the browser and run arbitrary code by presenting a specially crafted certificate to the client. This code provided compatibility with the non-standard regular expression syntax historically supported by Netscape clients and servers. With version 3.5 Firefox switched to the more limited industry-standard wildcard syntax instead and is not vulnerable to this flaw.
MFSA 2009-42 / CVE-2009-2408: IOActive security researcher Dan Kaminsky reported a mismatch in the treatment of domain names in SSL certificates between SSL clients and the Certificate Authorities (CA) which issue server certificates. In particular, if a malicious person requested a certificate for a host name with an invalid null character in it most CAs would issue the certificate if the requester owned the domain specified after the null, while most SSL clients (browsers) ignored that part of the name and used the unvalidated part in front of the null. This made it possible for attackers to obtain certificates that would function for any site they wished to target.
These certificates could be used to intercept and potentially alter encrypted communication between the client and a server such as sensitive bank account transactions. This vulnerability was independently reported to us by researcher Moxie Marlinspike who also noted that since Firefox relies on SSL to protect the integrity of security updates this attack could be used to serve malicious updates.
Mozilla would like to thank Dan and the Microsoft Vulnerability Research team for coordinating a multiple-vendor response to this problem.
The update also contains the fixes from the skipped 1.1.17 security update: MFSA 2009-17/CVE-2009-1307: Same-origin violations when Adobe Flash loaded via view-source: scheme
MFSA 2009-21/CVE-2009-1311:POST data sent to wrong site when saving web page with embedded frame
MFSA 2009-24/CVE-2009-1392/CVE-2009-1832/CVE-2009-1833: Crashes with evidence of memory corruption (rv:220.127.116.11)
MFSA 2009-26/CVE-2009-1835: Arbitrary domain cookie access by local file: resources
MFSA 2009-27/CVE-2009-1836: SSL tampering via non-200 responses to proxy CONNECT requests
MFSA 2009-29/CVE-2009-1838: Arbitrary code execution using event listeners attached to an element whose owner document is null
