Firefox < 31.0 Multiple Vulnerabilities (Mac OS X)

Critical Nessus Plugin ID 76759


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


The version of Firefox installed on the remote host is a version prior to 31.0. It is, therefore, affected by the following vulnerabilities :

- When a pair of NSSCertificate structures are added to a trust domain and then one of them is removed during use, a use-after-free error occurs which may cause the application to crash. This crash is potentially exploitable. (CVE-2014-1544)

- There are multiple memory safety hazards within the browser engine. These hazards may lead to memory corruption vulnerabilities, which may allow attackers to execute arbitrary code. (CVE-2014-1547, CVE-2014-1548)

- A buffer overflow exists when interacting with the Web Audio buffer during playback due to an error with the allocation of memory for the buffer. This may lead to a potentially exploitable crash. (CVE-2014-1549)

- A use-after-free exists in Web Audio due to the way control messages are handled. This may lead to a potentially exploitable crash. (CVE-2014-1550)

- There is an issue with the IFRAME sandbox same-origin access policy which allows sandboxed content to access other content from the same origin without approval.
This may lead to a same-origin-bypass vulnerability.

- Triggering the FireOnStateChange event has the potential to crash the application. This may lead to a use-after-free and an exploitable crash.

- When using the Cesium JavaScript library to generate WebGL content, the application may crash. This crash is potentially exploitable. (CVE-2014-1556)

- There is a flaw in the Skia library when scaling images of high quality. If the image data is discarded while being processed, the library may crash. This crash is potentially exploitable. (CVE-2014-1557)

- There are multiple issues with using invalid characters in various certificates. These invalid characters may cause certificates to be parsed incorrectly which may lead to the inability to use valid SSL certificates. (CVE-2014-1558, CVE-2014-1559, CVE-2014-1560)

- It may be possible to spoof drag and drop events in web content. This may allow limited ability to interact with the UI. (CVE-2014-1561)


Upgrade to Firefox 31.0 or later.
