CentOS Errata and Security Advisory CESA-2005:789

Mozilla is an open source Web browser, advanced email and newsgroup client, IRC chat client, and HTML editor.

A bug was found in the way Mozilla processes XBM image files. If a user views a specially crafted XBM file, it becomes possible to execute arbitrary code as the user running Mozilla. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-2701 to this issue.

A bug was found in the way Mozilla processes certain Unicode sequences. It may be possible to execute arbitrary code as the user running Mozilla, if the user views a specially crafted Unicode sequence. (CAN-2005-2702)

A bug was found in the way Mozilla makes XMLHttp requests. It is possible that a malicious web page could leverage this flaw to exploit other proxy or server flaws from the victim's machine. It is also possible that this flaw could be leveraged to send XMLHttp requests to hosts other than the originator; the default behavior of the browser is to disallow this. (CAN-2005-2703)

A bug was found in the way Mozilla implemented its XBL interface. It may be possible for a malicious web page to create an XBL binding in a way that would allow arbitrary JavaScript execution with chrome permissions. Please note that in Mozilla 1.7.10 this issue is not directly exploitable and would need to leverage other unknown exploits. (CAN-2005-2704)

An integer overflow bug was found in Mozilla's JavaScript engine. Under favorable conditions, it may be possible for a malicious web page to execute arbitrary code as the user running Mozilla. (CAN-2005-2705)

A bug was found in the way Mozilla displays about: pages. It is possible for a malicious web page to open an about: page, such as about:mozilla, in such a way that it becomes possible to execute JavaScript with chrome privileges. (CAN-2005-2706)

A bug was found in the way Mozilla opens new windows. It is possible for a malicious web site to construct a new window without any user interface components, such as the address bar and the status bar. This window could then be used to mislead the user for malicious purposes. (CAN-2005-2707)

Users of Mozilla are advised to upgrade to this updated package that contains Mozilla version 1.7.12 and is not vulnerable to these issues.
