(RHSA-2008:0978) Critical: firefox security update

Mozilla Firefox is an open source Web browser.

Several flaws were found in the processing of 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-2008-0017, CVE-2008-5014, CVE-2008-5016, CVE-2008-5017,
CVE-2008-5018, CVE-2008-5019, CVE-2008-5021)

Several flaws were found in the way malformed content was processed. A web
site containing specially-crafted content could potentially trick a Firefox
user into surrendering sensitive information. (CVE-2008-5022,
CVE-2008-5023, CVE-2008-5024)

A flaw was found in the way Firefox opened “file:” URIs. If a file: URI was
loaded in the same tab as a chrome or privileged “about:” page, the file:
URI could execute arbitrary code with the permissions of the user running
Firefox. (CVE-2008-5015)

For technical details regarding these flaws, please see the Mozilla
security advisories for Firefox 3.0.4. You can find a link to the Mozilla
advisories in the References section.

All firefox users should upgrade to these updated packages, which contain
backported patches that correct these issues.
