Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D

Multiple vulnerabilities have been reported in Mozilla Firefox,
Thunderbird, SeaMonkey and XULRunner, some of which may allow
user-assisted arbitrary remote code execution.

Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

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
=66rom 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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

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
=3D=3D=3D=3D=3D=3D

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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

There is no known workaround at this time.
