CentOS Errata and Security Advisory CESA-2009:0315

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-2009-0040, CVE-2009-0771, CVE-2009-0772, CVE-2009-0773, CVE-2009-0774,
CVE-2009-0775)

Several flaws were found in the way malformed content was processed. A
website containing specially-crafted content could, potentially, trick a
Firefox user into surrendering sensitive information. (CVE-2009-0776,
CVE-2009-0777)

For technical details regarding these flaws, please see the Mozilla
security advisories for Firefox 3.0.7. You can find a link to the Mozilla
advisories in the References section of this errata.

All Firefox users should upgrade to these updated packages, which contain
Firefox version 3.0.7, and which correct these issues. After installing the
update, Firefox must be restarted for the changes to take effect.
