(RHSA-2010:0680) Critical: seamonkey security update

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.
