3. Description:

SeaMonkey is an open source web browser, email and newsgroup client, IRC
chat client, and HTML editor.

Several flaws were found in the processing of malformed web content. A web
page containing malicious content could cause SeaMonkey to crash or,
potentially, execute arbitrary code with the privileges of the user running
SeaMonkey. (CVE-2010-3169)

A buffer overflow flaw was found in SeaMonkey. A web page containing
malicious content could cause SeaMonkey to crash or, potentially, execute
arbitrary code with the privileges of the user running SeaMonkey.
(CVE-2010-2765)

A use-after-free flaw and several dangling pointer flaws were found in
SeaMonkey. A web page containing malicious content could cause SeaMonkey to
crash or, potentially, execute arbitrary code with the privileges of the
user running SeaMonkey. (CVE-2010-2760, CVE-2010-2767, CVE-2010-3167,
CVE-2010-3168)

A cross-site scripting (XSS) flaw was found in SeaMonkey. A web page
containing malicious content could cause SeaMonkey to run JavaScript code
with the permissions of a different website. (CVE-2010-2768)

All SeaMonkey users should upgrade to these updated packages, which correct
these issues. After installing the update, SeaMonkey must be restarted for
the changes to take effect.
