Synopsis

Type/Severity

Security Advisory Critical

Topic

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.

Description

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 possibly lead to arbitrary code execution with the privileges of the user running SeaMonkey. (CVE-2011-0080)

An arbitrary memory write flaw was found in the way SeaMonkey handled out-of-memory conditions. If all memory was consumed when a user visited a malicious web page, it could possibly lead to arbitrary code execution with the privileges of the user running SeaMonkey. (CVE-2011-0078)

An integer overflow flaw was found in the way SeaMonkey handled the HTML frameset tag. A web page with a frameset tag containing large values for the "rows" and "cols" attributes could trigger this flaw, possibly leading to arbitrary code execution with the privileges of the user running SeaMonkey. (CVE-2011-0077)

A flaw was found in the way SeaMonkey handled the HTML iframe tag. A web page with an iframe tag containing a specially-crafted source address could trigger this flaw, possibly leading to arbitrary code execution with the privileges of the user running SeaMonkey. (CVE-2011-0075)

A flaw was found in the way SeaMonkey displayed multiple marquee elements. A malformed HTML document could cause SeaMonkey to execute arbitrary code with the privileges of the user running SeaMonkey. (CVE-2011-0074)

A flaw was found in the way SeaMonkey handled the nsTreeSelection element. Malformed content could cause SeaMonkey to execute arbitrary code with the privileges of the user running SeaMonkey. (CVE-2011-0073)

A use-after-free flaw was found in the way SeaMonkey appended frame and iframe elements to a DOM tree when the NoScript add-on was enabled. Malicious HTML content could cause SeaMonkey to execute arbitrary code with the privileges of the user running SeaMonkey. (CVE-2011-0072)

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.
