Firefox ESR 45.x < 45.3 Multiple Vulnerabilities (Mac OS X)

critical Nessus Plugin ID 92752

Synopsis

The remote Mac OS X host contains a web browser that is affected by multiple vulnerabilities.

Description

The version of Firefox ESR installed on the remote Mac OS X host is 45.x prior to 45.3. It is, therefore, affected by multiple vulnerabilities :

- An information disclosure vulnerability exists due to a failure to close connections after requesting favicons.
An attacker can exploit this to continue to send requests to the user's browser and disclose sensitive information.(CVE-2016-2830)

- Multiple memory corruption issues exist due to improper validation of user-supplied input. An attacker can exploit these issues to cause a denial of service condition or the execution of arbitrary code.
(CVE-2016-2835, CVE-2016-2836)

- An overflow condition exists in the ClearKey Content Decryption Module (CDM) used by the Encrypted Media Extensions (EME) API due to improper validation of user-supplied input. An attacker can exploit this to cause a buffer overflow, resulting in a denial of service condition or the execution of arbitrary code.
(CVE-2016-2837)

- An overflow condition exists in the ProcessPDI() function in layout/base/nsBidi.cpp due to improper validation of user-supplied input. An attacker can exploit this to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-2838)

- An underflow condition exists in the BasePoint4d() function in gfx/2d/Matrix.h due to improper validation of user-supplied input when calculating clipping regions in 2D graphics. A remote attacker can exploit this to cause a stack-based buffer underflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-5252)

- A use-after-free error exists in the KeyDown() function in layout/xul/nsXULPopupManager.cpp when using the alt key in conjunction with top level menu items. An attacker can exploit this to dereference already freed memory, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-5254)

- A use-after-free error exists in WebRTC that is triggered when handling DTLS objects. An attacker can exploit this to dereference already freed memory, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-5258)

- A use-after-free error exists in the DestroySyncLoop() function in dom/workers/WorkerPrivate.cpp that is triggered when handling nested sync event loops in Service Workers. An attacker can exploit this to dereference already freed memory, resulting in a denial of service condition or the execution of arbitrary code.
(CVE-2016-5259)

- A security bypass vulnerability exists due to event handler attributes on a <marquee> tag being executed inside a sandboxed iframe that does not have the allow-scripts flag set. An attacker can exploit this to bypass cross-site scripting protection mechanisms.
(CVE-2016-5262)

- A type confusion flaw exists in the HitTest() function in nsDisplayList.cpp when handling display transformations. An attacker can exploit this to execute arbitrary code. (CVE-2016-5263)

- A use-after-free error exists in the NativeAnonymousChildListChange() function when applying effects to SVG elements. An attacker can exploit this to dereference already freed memory, resulting in a denial of service condition or the execution of arbitrary code.
(CVE-2016-5264)

- A flaw exists in the Redirect() function in nsBaseChannel.cpp that is triggered when a malicious shortcut is called from the same directory as a local HTML file. An attacker can exploit this to bypass the same-origin policy. (CVE-2016-5265)

Solution

Upgrade to Firefox ESR version 45.3 or later.
