Synopsis
========

Multiple vulnerabilities have been reported in Mozilla Firefox, some of
which may allow the remote execution of arbitrary code.

Background
==========

Mozilla Firefox is a popular open-source web browser from the Mozilla
Project.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-client/mozilla-firefox lt; 1.5.0.9 gt;= 1.5.0.9
2 www-client/mozilla-firefox-bin lt; 1.5.0.9 gt;= 1.5.0.9
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------

Description
===========

An anonymous researcher found evidence of memory corruption in the way
Mozilla Firefox handles certain types of SVG comment DOM nodes.
Additionally, Frederik Reiss discovered a heap-based buffer overflow in
the conversion of a CSS cursor. Other issues with memory corruption
were also fixed. Mozilla Firefox also contains less severe
vulnerabilities involving JavaScript and Java.

Impact
======

An 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. It is also possible for an attacker to
perform cross-site scripting attacks, leading to the exposure of
sensitive information, like user credentials.

Workaround
==========

There are no known workarounds for all the issues at this time.

Resolution
==========

All Mozilla Firefox users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose "gt;=www-client/mozilla-firefox-1.5.0.9"

All Mozilla Firefox binary release users should upgrade to the latest
version:

# emerge --sync
# emerge --ask --oneshot --verbose "gt;=www-client/mozilla-firefox-bin-1.5.0.9"
