Vulnerability Assessment Details

[GLSA-200503-31] Mozilla Firefox: Multiple vulnerabilities

Vulnerability Assessment Summary
Mozilla Firefox: Multiple vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200503-31
(Mozilla Firefox: Multiple vulnerabilities)

The following vulnerabilities were found and fixed in Mozilla
Firefox:
Mark Dowd from ISS X-Force reported an
exploitable heap overrun in the GIF processing of obsolete Netscape
extension 2 (CVE-2005-0399)
Kohei Yoshino discovered that a
page bookmarked as a sidebar could bypass rights control
(CVE-2005-0402)
Michael Krax reported a new way to bypass XUL
security restrictions through drag-and-drop of items like scrollbars
(CVE-2005-0401)

Impact

The GIF heap overflow could be triggered by a malicious GIF
image that would end up executing arbitrary code with the rights of the
user running Firefox
By tricking the user into bookmarking a
malicious page as a Sidebar, a remote attacker could potentially
execute arbitrary code with the rights of the user running the
browser
By setting up a malicious website and convincing users
to obey very specific drag-and-drop instructions, attackers may
leverage drag-and-drop features to bypass XUL security restrictions,
which could be used as a stepping stone to exploit other
vulnerabilities

Workaround

There is no known workaround at this time.
