The remote Red Hat host is missing one or more security updates.
Updated SeaMonkey packages that fix several security issues are now
available for Red Hat Enterprise Linux 3 and 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.
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-2010-3176, CVE-2010-3180)
A flaw was found in the way the Gopher parser in SeaMonkey converted
text into HTML. A malformed file name on a Gopher server could, when
be executed in the context of the Gopher domain. (CVE-2010-3177)
A flaw was found in the script that launches SeaMonkey. The
LD_LIBRARY_PATH variable was appending a '.' character, which could
allow a local attacker to execute arbitrary code with the privileges
of a different user running SeaMonkey, if that user ran SeaMonkey from
within an attacker-controlled directory. (CVE-2010-3182)
It was found that the SSL DHE (Diffie-Hellman Ephemeral) mode
implementation for key exchanges in SeaMonkey accepted DHE keys that
were 256 bits in length. This update removes support for 256 bit DHE
keys, as such keys are easily broken using modern hardware.
A flaw was found in the way SeaMonkey matched SSL certificates when
the certificates had a Common Name containing a wildcard and a partial
IP address. SeaMonkey incorrectly accepted connections to IP addresses
that fell within the SSL certificate's wildcard range as valid SSL
connections, possibly allowing an attacker to conduct a
man-in-the-middle attack. (CVE-2010-3170)
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.
