The remote host is missing updates announced in
advisory RHSA-2011:0888.
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 malformed JPEG images. A
website containing a malicious JPEG image could cause SeaMonkey to crash
or, potentially, execute arbitrary code with the privileges of the user
running SeaMonkey. (CVE-2011-2377)
Multiple 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-2011-0083, CVE-2011-0085, CVE-2011-2363)
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-2011-2364, CVE-2011-2365, CVE-2011-2374, CVE-2011-2375,
CVE-2011-2376)
An integer overflow flaw was found in the way SeaMonkey handled JavaScript
Array objects. A website containing malicious JavaScript could cause
SeaMonkey to execute that JavaScript with the privileges of the user
running SeaMonkey. (CVE-2011-2371)
A use-after-free flaw was found in the way SeaMonkey handled malformed
JavaScript. A website containing malicious JavaScript could cause SeaMonkey
to execute that JavaScript with the privileges of the user running
SeaMonkey. (CVE-2011-2373)
It was found that SeaMonkey could treat two separate cookies as
interchangeable if both were for the same domain name but one of those
domain names had a trailing . character. This violates the same-origin
policy and could possibly lead to data being leaked to the wrong domain.
(CVE-2011-2362)
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.
