devhelp, seamonkey security update

CentOS Errata and Security Advisory CESA-2006:0676

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)

A flaw was found in the handling of Javascript timed events. A malicious
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. An attacker 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)

A flaw was found in SeaMonkey Messenger triggered when a HTML message
contained a remote image pointing to a XBL script. An attacker could have
created a carefully crafted message which would execute Javascript if
certain actions were performed on the email by the recipient, even if
Javascript was disabled. (CVE-2006-4570)

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.
