Descriptions

Use-after-free vulnerability in the TypeObject class in the JavaScript engine in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 allows remote attackers to execute arbitrary code by triggering extensive memory consumption while garbage collection is occurring, as demonstrated by improper handling of BumpChunk objects.

Vulnerabilidad de uso después de liberación en la clase TypeObject en el motor JavaScript en Mozilla Firefox anterior a 28.0, Firefox ESR 24.x anterior a 24.4, Thunderbird anterior a 24.4 y SeaMonkey anterior a 2.25 permite a atacantes remotos ejecutar código arbitrario mediante el aprovechamiento del consumo de memoria extensivo mientras la recolección de basura está ocurriendo.

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 TypeObjects. By manipulating a document's elements an attacker can force a dangling pointer to be reused after it has been freed. An attacker can leverage this vulnerability to execute code under the context of the current process.
