 (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)

The remote host is affected by the vulnerability described in GLSA-201605-06 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Firefox, NSS, NSPR, and       Thunderbird. Please review the CVE identifiers referenced below for       details.
  Impact :

    A remote attacker could entice a user to view a specially crafted web       page or email, possibly resulting in execution of arbitrary code or a       Denial of Service condition. Furthermore, a remote attacker may be able       to perform Man-in-the-Middle attacks, obtain sensitive information, spoof       the address bar, conduct clickjacking attacks, bypass security       restrictions and protection mechanisms, or have other unspecified       impacts.
  Workaround :

    There is no known workaround at this time.

The version of Firefox is prior to 44.0 and is affected by multiple vulnerabilities : 

 - Multiple unspecified memory corruption issues exist that allow a remote attacker to execute arbitrary code. (CVE-2016-1930, CVE-2016-1931)
 - An integer overflow condition exists due to improper parsing of GIF images during deinterlacing. A remote attacker can exploit this, via a specially crafted GIF image, to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-1933)
 - A buffer overflow condition exists in WebGL that is triggered when handling cache out-of-memory error conditions. A remote attacker can exploit this to execute arbitrary code. (CVE-2016-1935)
 - A content spoofing vulnerability exists due to the protocol handler dialog treating double click events as two single click events. A remote attacker can exploit this to spoof content, allowing the attacker to trick a user into performing malicious actions. (CVE-2016-1937)
 - A cryptographic weakness exists in Network Security Services (NSS) due to incorrect calculations with 'mp_div' and 'mp_exptmod'. (CVE-2016-1938)
 - A cookie injection vulnerability exists due to illegal control characters being permitted in cookie names. A remote attacker can exploit this to inject cookies. (CVE-2016-1939)
 - A flaw exists 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)
 - An URL spoofing vulnerability exists due to a flaw that is triggered during the handling of a URL that invalid for the internal protocol, causing the URL to be pasted into the address bar. A remote attacker can exploit this spoof URLs, allowing the attacker to trick a user into visiting a malicious website. (CVE-2016-1942)
 - An unspecified memory corruption issue exists in the ANGLE graphics library implementation. A remote attacker can exploit this to corrupt memory, resulting in the execution of arbitrary code. (CVE-2016-1944)
 - A wild pointer flaw exists due to improper handling of ZIP files. A remote attacker can exploit this, via a crafted ZIP file, to have an unspecified impact. (CVE-2016-1945)
 - An integer overflow condition exists in the bundled version of libstagefright due to improper handling of MP4 file metadata. A remote attacker can exploit this to execute arbitrary code. (CVE-2016-1946)
 - A flaw exists in the safe browsing feature due to the Application Reputation service being unreachable. A remote attacker can exploit this to convince a user into downloading a malicious executable without being warned. (CVE-2016-1947)
