Firefox ESR 24.x < 24.7 Multiple Vulnerabilities

High Nessus Plugin ID 76762


The remote Windows host contains a web browser that is affected by multiple vulnerabilities.


The version of Firefox ESR 24.x installed on the remote host is prior to 24.7. 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)

- There is a potential use-after-free issue in DirectWrite font handling. This may allow an attacker to potentially execute arbitrary code within the context of the user running the application. (CVE-2014-1551)

- 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)


Upgrade to Firefox ESR 24.7 or later.
