Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2011:0313
The remote host is missing updates announced in
advisory RHSA-2011:0313.

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

A flaw was found in the way SeaMonkey handled dialog boxes. An attacker
could use this flaw to create a malicious web page that would present a
blank dialog box that has non-functioning buttons. If a user closes the
dialog box window, it could unexpectedly grant the malicious web page
elevated privileges. (CVE-2011-0051)

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-2011-0053)

A flaw was found in the way SeaMonkey handled plug-ins that perform HTTP
requests. If a plug-in performed an HTTP request, and the server sent a 307
redirect response, the plug-in was not notified, and the HTTP request was
forwarded. The forwarded request could contain custom headers, which could
result in a Cross Site Request Forgery attack. (CVE-2011-0059)

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.

Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
