Mozilla products: Multiple vulnerabilities

Background

Mozilla Firefox is an open-source web browser from the Mozilla Project, and Mozilla Thunderbird an email client. The SeaMonkey project is a community effort to deliver production-quality releases of code derived from the application formerly known as the ‘Mozilla Application Suite’. XULRunner is a Mozilla runtime package that can be used to bootstrap XUL+XPCOM applications like Firefox and Thunderbird.

Description

Mozilla developers fixed several bugs involving memory corruption through various vectors (CVE-2007-2867, CVE-2007-2868). Additionally, several errors leading to crash, memory exhaustion or CPU consumption were fixed (CVE-2007-1362, CVE-2007-2869). Finally, errors related to the APOP protocol (CVE-2007-1558), XSS prevention (CVE-2007-2870) and spoofing prevention (CVE-2007-2871) were fixed.

Impact

A remote attacker could entice a user to view a specially crafted web page that will trigger one of the vulnerabilities, possibly leading to the execution of arbitrary code or a Denial of Service. It is also possible for an attacker to spoof the address bar or other browser elements, obtain sensitive APOP information, or perform cross-site scripting attacks, leading to the exposure of sensitive information, like user credentials.

Workaround

There is no known workaround at this time.
