December 21, 2009 09:19 Ubuntu: New Firefox/Xulrunner packages fix vulnerabilities

0

Jesse Ruderman, Josh Soref, Martijn Wargers, Jose Angel, Olli Pettay, and David James discovered several flaws in the browser and JavaScript engines of Firefox. If a user were tricked into viewing a malicious website, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. Takeiro Takahashi discovered flaws in the NTLM implementation in Firefox. If an NTLM authenticated user visited a malicious website, a remote attacker could send requests to other applications, authenticated as the user. Jonathan Morgan discovered that Firefox did not properly display SSL indicators under certain circumstances. This could be used by an attacker to spoof an encrypted page, such as in a phishing attack. Jordi Chancel discovered that Firefox did not properly display invalid URLs for a blank page. If a user were tricked into accessing a malicious website, an attacker could exploit this to spoof the location bar, such as in a phishing attack. David Keeler, Bob Clary, and Dan Kaminsky discovered several flaws in third party media libraries. If a user were tricked into opening a crafted media file, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. Updated packages are available from security.ubuntu.com.

Multiple insecure temporary file handling vulnerabilities were discovered in Red Hat Cluster. A local attacker could exploit these to overwrite arbitrary local files via symlinks. It was discovered that CMAN did not properly handle malformed configuration files. An attacker could cause a denial of service (via CPU consumption and memory corruption) in a node if the attacker were able to modify the cluster configuration for the node. Updated packages are available from security.ubuntu.com.
