GLSA 200701-02: Mozilla Firefox: Multiple vulnerabilities

Severity:normal
Title:Mozilla Firefox: Multiple vulnerabilities
Date:01/04/2007
Bugs: #156023
ID:200701-02

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 Architecture(s)
www-client/mozilla-firefox < 1.5.0.9 >= 1.5.0.9 All supported architectures
www-client/mozilla-firefox-bin < 1.5.0.9 >= 1.5.0.9 All 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 ">=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 ">=www-client/mozilla-firefox-bin-1.5.0.9"
