RHSA-2007:0979 - 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 in which Firefox processed certain
malformed web content. A web page containing malicious content could cause
Firefox to crash or potentially execute arbitrary code as the user running
Firefox. (CVE-2007-5338, CVE-2007-5339, CVE-2007-5340)

Several flaws were found in the way in which Firefox displayed malformed
web content. A web page containing specially-crafted content could
potentially trick a user into surrendering sensitive information.
(CVE-2007-1095, CVE-2007-3844, CVE-2007-3511, CVE-2007-5334)

A flaw was found in the Firefox sftp protocol handler. A malicious web page
could access data from a remote sftp site, possibly stealing sensitive user
data. (CVE-2007-5337)

A request-splitting flaw was found in the way in which Firefox generates a
digest authentication request. If a user opened a specially-crafted URL, it
was possible to perform cross-site scripting attacks, web cache poisoning,
or other, similar exploits. (CVE-2007-2292)

All users of Firefox are advised to upgrade to these updated packages,
which contain backported patches that correct these issues.
