Descriptions

Use-after-free vulnerability in DirectionalityUtils.cpp in Mozilla Firefox before 32.0, Firefox ESR 24.x before 24.8 and 31.x before 31.1, and Thunderbird 24.x before 24.8 and 31.x before 31.1 allows remote attackers to execute arbitrary code via text that is improperly handled during the interaction between directionality resolution and layout.

Vulnerabilidad de uso después de liberación en DirectionalityUtils.cpp en Mozilla Firefox anterior a 32.0, Firefox ESR 24.x anterior a 24.8 y 31.x anterior a 31.1 y Thunderbird 24.x anterior a 24.8 y 31.x anterior a 31.1 permite a atacantes remotos ejecutar código arbitrario a través de texto que no se maneja debidamente durante la interacción entre la resolución de la direccionalidad y el diseño.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Mozilla Firefox. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the handling of bi-directional unicode text. The issue lies in the failure to properly handle text that has its bi-directional character type changed. An attacker can leverage this vulnerability to execute code under the context of the current process.
