Mozilla is an open source Web browser, advanced email and newsgroup client, IRC chat client, and HTML editor. Several bugs were found in the way Mozilla executes javascript code. Javascript executed from a web page should run with a restricted access level, preventing dangerous actions. It is possible that a malicious web page could execute javascript code with elevated privileges, allowing access to protected data and functions. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2005-1476, CAN-2005-1477, CAN-2005-1531, and CAN-2005-1532 to these issues. Users of Mozilla are advised to upgrade to this updated package, which contains Mozilla version 1.7.8 to correct these issues.
