Hat Security Response Team.

Description

Mozilla Firefox is an open source Web browser.

Several flaws were found in the processing of some malformed web content. A
web page containing such malicious content could cause Firefox to crash or,
potentially, execute arbitrary code as the user running Firefox.
(CVE-2008-1233, CVE-2008-1235, CVE-2008-1236, CVE-2008-1237)

Several flaws were found in the display of malformed web content. A web
page containing specially-crafted content could, potentially, trick a
Firefox user into surrendering sensitive information. (CVE-2008-1234,
CVE-2008-1238, CVE-2008-1241)

All Firefox users should upgrade to these updated packages, which contain
