Mozilla Firefox: Multiple vulnerabilities — GLSA 200701-02

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

Affected Packages

www-client/mozilla-firefox on all architectures
Affected versions < 1.5.0.9
Unaffected versions >= 1.5.0.9
www-client/mozilla-firefox-bin on all architectures
Affected versions < 1.5.0.9
Unaffected versions >= 1.5.0.9

Background

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

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"
