RHSA-2006:0759 - Security Advisory

Topic

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
Hat Security Response Team.

Description

SeaMonkey is an open source Web browser, advanced email and newsgroup
client, IRC chat client, and HTML editor.

Several flaws were found in the way SeaMonkey processes certain malformed
Javascript code. A malicious web page could cause the execution of
Javascript code in such a way that could cause SeaMonkey to crash or
execute arbitrary code as the user running SeaMonkey. (CVE-2006-6498,
CVE-2006-6501, CVE-2006-6502, CVE-2006-6503, CVE-2006-6504)

Several flaws were found in the way SeaMonkey renders web pages. A
malicious web page could cause the browser to crash or possibly execute
arbitrary code as the user running SeaMonkey. (CVE-2006-6497)

A heap based buffer overflow flaw was found in the way SeaMonkey Mail
parses the Content-Type mail header. A malicious mail message could cause
the SeaMonkey Mail client to crash or possibly execute arbitrary code as
the user running SeaMonkey Mail. (CVE-2006-6505)

Users of SeaMonkey are advised to upgrade to these erratum packages, which
contain SeaMonkey version 1.0.7 that corrects these issues.
