• Mozilla Network Security Services (NSS) contains an unspecified cryptographical issue when handling calculations that contain mp_div or mp_exptmod. This may allow an attacker to trigger potential cryptographic weaknesses. (CVE-2016-1938)

• Mozilla Firefox for Android contains a flaw in mobile/android/chrome/content/browser.js that is triggered as lightweight themes fail to properly secure connections when installing themes. This may allow a remote man-in-the-middle attacker to make changes to the theme.
  (CVE-2016-1948)

• Mozilla Firefox contains a flaw in the protocol handler in toolkit/mozapps/handling/content/dialog.js that is due to the handler treating double click events as two single click events. This may allow a context-dependent attacker to spoof content to cause a user to potentially perform malicious actions, such as downloading attacker controlled software. (CVE-2016-1937)

• Mozilla Firefox for Mac OS X contains a flaw that is triggered as the delay between the download dialog getting focus and the button getting enabled is too short. If a context-dependent attacker can trick a user into double clicking in a specific location, they can pass the second click through to a dialog below that location. This will allow the attacker to cause the user to perform unintentional actions. (CVE-2016-1941)

• Mozilla Firefox contains a flaw in browser/base/content/urlbarBindings.xml that is triggered during the handling of a URL that is invalid for the internal protocol, which will cause the URL to be pasted into the address bar. This may allow a context-dependent attacker to spoof URLs. (CVE-2016-1942)

• Mozilla Network Security Services (NSS) contains a use-after-free error in the ssl3_HandleECDHServerKeyExchange() function. The issue is triggered when handling failed allocations during DHE and ECDHE handshakes. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2016-1978)
