Mozilla Firefox was updated to the 3.6.17 security release.

  - Mozilla developers identified and fixed several memory     safety bugs in the browser engine used in Firefox and     other Mozilla-based products. Some of these bugs showed     evidence of memory corruption under certain     circumstances, and we presume that with enough effort at     least some of these could be exploited to run arbitrary     code.

  - Security researcher regenrecht reported several dangling     pointer vulnerabilities via TippingPoint's Zero Day     Initiative. (MFSA 2011-13 / CVE-2011-0065 /     CVE-2011-0066 / CVE-2011-0073)

  - Security researcher Paul Stone reported that a Java     applet could be used to mimic interaction with form     autocomplete controls and steal entries from the form     history. (MFSA 2011-14 / CVE-2011-0067)

  - David Remahl of Apple Product Security reported that the     Java Embedding Plugin (JEP) shipped with the Mac OS X     versions of Firefox could be exploited to obtain     elevated access to resources on a user's system. (MFSA     2011-15 / CVE-2011-0076)

  - Security researcher Soroush Dalili reported that the     resource: protocol could be exploited to allow directory     traversal on Windows and the potential loading of     resources from non-permitted locations. The impact would     depend on whether interesting files existed in     predictable locations in a useful format. For example,     the existence or non-existence of particular images     might indicate whether certain software was installed.
    (MFSA 2011-16 / CVE-2011-0071)

  - Chris Evans of the Chrome Security Team reported that     the XSLT generate-id() function returned a string that     revealed a specific valid address of an object on the     memory heap. It is possible that in some cases this     address would be valuable information that could be used     by an attacker while exploiting a different memory     corruption but, in order to make an exploit more     reliable or work around mitigation features in the     browser or operating system. (MFSA 2011-18 /     CVE-2011-1202)
