Mozilla layout engine contains multiple vulnerabilities

Vulnerability Note VU#761756

Original Release Date: 2007-02-26 | Last Revised: 2007-03-08


The Mozilla layout engine contains multiple memory corruption vulnerabilities. These vulnerabilities may allow an attacker to execute arbitrary code, or create a denial of service condition.


The Mozilla Foundation supports several Open Source projects, including the Mozilla, Seamonkey, and Firefox web browsers. The Thunderbird email client is also a Mozilla product. These products use the Mozilla layout engine to render HTML formatted text.

The Mozilla layout engine contains multiple vulnerabilities. An attacker may be able to exploit these vulnerabilties by convincing a user to connect to a specially crafted website or viewing an HTML formatted email. For more information refer to Mozilla Foundation Security Advisory 2007-01.


A remote, unauthenticated attacker may be able to execute arbitrary code or create a denial of service condition.


See Mozilla Foundation Security Advisory 2007-01 for information about affected clients.

Configuring Thunderbird to display email in plain text may partially mitigate this vulnerability.
