RHEL 2.1 / 3 / 4 : seamonkey (RHSA-2006:0676)
Critical Nessus Plugin ID 22358
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated SeaMonkey packages that fix several security bugs are now available for Red Hat Enterprise Linux 2.1, 3, and 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.
Two flaws were found in the way SeaMonkey processed certain regular expressions. A malicious web page could crash the browser or possibly execute arbitrary code as the user running SeaMonkey. (CVE-2006-4565, CVE-2006-4566)
Daniel Bleichenbacher recently described an implementation error in RSA signature verification. For RSA keys with exponent 3 it is possible for an attacker to forge a signature that would be incorrectly verified by the NSS library. SeaMonkey as shipped trusts several root Certificate Authorities that use exponent 3. An attacker could have created a carefully crafted SSL certificate which be incorrectly trusted when their site was visited by a victim.
SeaMonkey did not properly prevent a frame in one domain from injecting content into a sub-frame that belongs to another domain, which facilitates website spoofing and other attacks (CVE-2006-4568)
A number of flaws were found in SeaMonkey. A malicious web page could crash the browser or possibly execute arbitrary code as the user running SeaMonkey. (CVE-2006-4571)
Users of SeaMonkey or Mozilla are advised to upgrade to this update, which contains SeaMonkey version 1.0.5 that corrects these issues.
For users of Red Hat Enterprise Linux 2.1 this SeaMonkey update obsoletes Galeon. Galeon was a web browser based on the Mozilla Gecko layout engine.
SolutionUpdate the affected packages.
