CVE-2016-9064

Add-on updates failed to verify that the add-on ID inside the signed package matched the ID of the add-on being updated. An attacker who could perform a man-in-the-middle attack on the user's connection to the update server and defeat the certificate pinning protection could provide a malicious signed add-on instead of a valid update. This vulnerability affects Firefox ESR < 45.5 and Firefox < 50.

Multiple 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-2016-5296, CVE-2016-5297, CVE-2016-9066, CVE-2016-5291, CVE-2016-5290).

A flaw was found in the way Add-on update process was handled by Firefox. A Man-in-the-Middle attacker could use this flaw to install a malicious signed add-on update (CVE-2016-9064).

An existing mitigation of timing side-channel attacks in NSS before 3.26.1 is insufficient in some circumstances (CVE-2016-9074).

Updated Iceape packages include security fixes from upstream Seamonkey:

Multiple flaws were found in the way Iceape 2.46 processes various types of web content, where loading a web page containing malicious content could cause Iceape to crash, execute arbitrary code, or disclose sensitive information.
