Detailed Explanation for this Vulnerability Assessment
Updated 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

web page could crash the browser or possibly execute arbitrary code as the
user running SeaMonkey. (CVE-2006-4253)
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. A possible hacker could have created a carefully crafted
SSL certificate which be incorrectly trusted when their site was visited by
a victim. (CVE-2006-4340)
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)
