Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated seamonkey packages that fix a security issues are now
available for Red Hat Enterprise Linux 2.1, Red Hat Enterprise Linux 3
and Red Hat Enterprise Linux 4.

This update has been rated as having critical security impact by the
Red Hat Security Response Team.

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

Multiple flaws were found in the processing of malformed JavaScript
content. A web page containing such malicious content could cause
SeaMonkey to crash or, potentially, execute arbitrary code as the user
running SeaMonkey. (CVE-2008-2801, CVE-2008-2802, CVE-2008-2803)

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 as the user running SeaMonkey.
(CVE-2008-2798, CVE-2008-2799, CVE-2008-2811)

Several flaws were found in the way malformed web content was
displayed. A web page containing specially-crafted content could
potentially trick a SeaMonkey user into surrendering sensitive
information. (CVE-2008-2800)

Two local file disclosure flaws were found in SeaMonkey. A web page
containing malicious content could cause SeaMonkey to reveal the
contents of a local file to a remote attacker. (CVE-2008-2805,
CVE-2008-2810)

A flaw was found in the way a malformed .properties file was processed
by SeaMonkey. A malicious extension could read uninitialized memory,
possibly leaking sensitive data to the extension. (CVE-2008-2807)

A flaw was found in the way SeaMonkey escaped a listing of local file
names. If a user could be tricked into listing a local directory
containing malicious file names, arbitrary JavaScript could be run
with the permissions of the user running SeaMonkey. (CVE-2008-2808)

A flaw was found in the way SeaMonkey displayed information about
self-signed certificates. It was possible for a self-signed
certificate to contain multiple alternate name entries, which were not
all displayed to the user, allowing them to mistakenly extend trust to
an unknown site. (CVE-2008-2809)

All SeaMonkey users should upgrade to these updated packages, which
contain backported patches to resolve these issues.
