タイプ/重大度

Security Advisory: Critical

トピック

Updated seamonkey packages that fix several security issues are now
available for Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having critical
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

説明

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.
