Mozilla is an open source Web browser, advanced email and newsgroup client,
IRC chat client, and HTML editor.

A buffer overflow bug was found in the way Mozilla processes GIF images. It
is possible for an attacker to create a specially crafted GIF image, which
when viewed by a victim will execute arbitrary code as the victim. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2005-0399 to this issue.

possible for a malicious webserver to steal credentials from a victims
browser by issuing a 407 proxy authentication request. (CAN-2005-0147)

A bug was found in the way Mozilla displays dialog windows. It is possible
that a malicious web page which is being displayed in a background tab
could present the user with a dialog window appearing to come from the
active page. (CAN-2004-1380)

A bug was found in the way Mozilla Mail handles cookies when loading
content over HTTP regardless of the user’s preference. It is possible that

messages which load content over HTTP. (CAN-2005-0149)

for a malicious website to control the content in an unrelated site’s

It is possible for a malicious web page to steal the contents of a victims
clipboard. (CAN-2005-0146)

middle clicked. A malicious web page could read local files or modify

A bug was found in the way Mozilla displays the secure site icon. A
malicious web page can use a view-source URL targetted at a secure page,
while loading an insecure page, yet the secure site icon shows the previous
secure state. (CAN-2005-0144)

A bug was found in the way Mozilla displays the secure site icon. A
malicious web page can display the secure site icon by loading a binary

Users of Mozilla are advised to upgrade to this updated package which
contains Mozilla version 1.7.6 to correct these issues.
