Description:

The remote host is affected by the vulnerability described in GLSA-200503-32
(Mozilla Thunderbird: Multiple vulnerabilities)


The following vulnerabilities were found and fixed in Mozilla
Thunderbird:
Mark Dowd from ISS X-Force reported an
exploitable heap overrun in the GIF processing of obsolete Netscape
extension 2 (CAN-2005-0399)
Daniel de Wildt and Gael Delalleau
discovered a memory overwrite in a string library (CAN-2005-0255)
Wind Li discovered a possible heap overflow in UTF8 to Unicode
conversion (CAN-2005-0592)
Phil Ringnalda reported a possible
way to spoof Install source with user:pass@host (CAN-2005-0590)

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 Thunderbird. The other overflow issues, while not thought to be
exploitable, would have the same impact. Furthermore, by setting up
malicious websites and convincing users to follow untrusted links,
attackers may leverage the spoofing issue to trick user into installing
malicious extensions.

Workaround

There is no known workaround at this time.
