Description

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.
