The remote host is missing updates announced in
advisory RHSA-2010:0861.
Mozilla Firefox is an open source web browser. XULRunner provides the XUL
Runtime environment for Mozilla Firefox.
A race condition flaw was found in the way Firefox handled Document Object
Model (DOM) element properties. Malicious HTML content could cause Firefox
to crash or, potentially, execute arbitrary code with the privileges of the
user running Firefox. (CVE-2010-3765)
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 with the privileges of the user running
Firefox. (CVE-2010-3175, CVE-2010-3176, CVE-2010-3179, CVE-2010-3183,
CVE-2010-3180)
A flaw was found in the way the Gopher parser in Firefox converted text
into HTML. A malformed file name on a Gopher server could, when accessed by
a victim running Firefox, allow arbitrary JavaScript to be executed in the
context of the Gopher domain. (CVE-2010-3177)
A same-origin policy bypass flaw was found in Firefox. An attacker could
create a malicious web page that, when viewed by a victim, could steal
private data from a different website the victim had loaded with Firefox.
(CVE-2010-3178)
A flaw was found in the script that launches Firefox. The LD_LIBRARY_PATH
variable was appending a . character, which could allow a local attacker
to execute arbitrary code with the privileges of a different user running
Firefox, if that user ran Firefox from within an attacker-controlled
directory. (CVE-2010-3182)
For technical details regarding these flaws, refer to the Mozilla security
advisories for Firefox 3.6.11 and 3.6.12. You can find links to the Mozilla
advisories in the References section of this erratum.
All Firefox users should upgrade to these updated packages, which contain
Firefox version 3.6.12, which corrects these issues. After installing the
update, Firefox must be restarted for the changes to take effect.
