RHSA-2010:0546 - Critical: seamonkey security update

Synopsis

Critical: seamonkey security update

Type/Severity

Security Advisory Critical

Topic

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.

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 cause SeaMonkey to crash or, potentially, execute arbitrary code with the privileges of the user running SeaMonkey. (CVE-2010-1211, CVE-2010-2753, CVE-2010-1214)

A memory corruption flaw was found in the way SeaMonkey decoded certain PNG images. An attacker could create a specially-crafted PNG image that, when opened, could cause SeaMonkey to crash or, potentially, execute arbitrary code with the privileges of the user running SeaMonkey. (CVE-2010-1205)

A same-origin policy bypass flaw was found in SeaMonkey. An attacker could create a malicious web page that, when viewed by a victim, could steal private data from a different website the victim has loaded with SeaMonkey. (CVE-2010-2754)

A flaw was found in the way SeaMonkey displayed the location bar when visiting a secure web page. A malicious server could use this flaw to present data that appears to originate from a secure server, even though it does not. (CVE-2010-2751)

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.
