Vulnerability Assessment Details

[GLSA-200501-03] Mozilla, Firefox, Thunderbird: Various vulnerabilities

Vulnerability Assessment Summary
Mozilla, Firefox, Thunderbird: Various vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200501-03
(Mozilla, Firefox, Thunderbird: Various vulnerabilities)


Maurycy Prodeus from isec.pl found a potentially exploitable
buffer overflow in the handling of NNTP URLs. Furthermore, Martin (from
ptraced.net) discovered that temporary files in recent versions of
Mozilla-based products were sometimes stored world-readable with
predictable names. The Mozilla Team also fixed a way of spoofing
filenames in Firefox's "What should Firefox do with this file" dialog
boxes and a potential information leak about the existence of local
filenames.

Impact

A remote attacker could craft a malicious NNTP link and entice a
user to click it, potentially resulting in the execution of arbitrary
code with the rights of the user running the browser. A local attacker
could leverage the temporary file vulnerability to read the contents of
another user's attachments or downloads. A remote attacker could also
design a malicious web page that would permit to spoof filenames if the
user uses the "Open with..." function in Firefox, or retrieve
information on the existence of specific files in the local filesystem.

Workaround

There is no known workaround at this time.
