Critical: firefox security update

Updated firefox packages that fix several security issues 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.

Mozilla Firefox is an open source Web browser.

Several flaws were found in the way Firefox processed certain malformed web
content. A webpage containing malicious content could cause Firefox to
crash, or potentially execute arbitrary code as the user running Firefox.
(CVE-2008-0412, CVE-2008-0413, CVE-2008-0415, CVE-2008-0419)

Several flaws were found in the way Firefox displayed malformed web
content. A webpage containing specially-crafted content could trick a user
into surrendering sensitive information. (CVE-2008-0591, CVE-2008-0593)

A flaw was found in the way Firefox stored password data. If a user saves
login information for a malicious website, it could be possible to corrupt
the password database, preventing the user from properly accessing saved
password data. (CVE-2008-0417)

A flaw was found in the way Firefox handles certain chrome URLs. If a user
has certain extensions installed, it could allow a malicious website to
steal sensitive session data. Note: this flaw does not affect a default
installation of Firefox. (CVE-2008-0418)

A flaw was found in the way Firefox saves certain text files. If a
website offers a file of type "plain/text", rather than "text/plain",
Firefox will not show future "text/plain" content to the user in the
browser, forcing them to save those files locally to view the content.
(CVE-2008-0592)

Users of firefox are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
