RHSA-2007:0724 - Security Advisory

Topic

Updated firefox packages that fix several security bugs are now available
for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having critical security impact by the Red
Hat Security Response Team.

Description

Mozilla Firefox is an open source Web browser.

Several flaws were found in the way Firefox processed certain malformed
JavaScript code. A web page containing malicious JavaScript code could
cause Firefox to crash or potentially execute arbitrary code as the user
running Firefox. (CVE-2007-3734, CVE-2007-3735, CVE-2007-3737, CVE-2007-3738)

Several content injection flaws were found in the way Firefox handled
certain JavaScript code. A web page containing malicious JavaScript code
could inject arbitrary content into other web pages. (CVE-2007-3736,
CVE-2007-3089)

A flaw was found in the way Firefox cached web pages on the local disk. A
malicious web page may be able to inject arbitrary HTML into a browsing
session if the user reloads a targeted site. (CVE-2007-3656)

Users of Firefox are advised to upgrade to these erratum packages, which
contain backported patches that correct these issues.
