CVE-2008-1026

Estado: ModificadaMedia (6.8)—

Desbordamiento de entero en el compilador de expresiones regulares PCRE (JavaScriptCore/pcre/pcre_compile.cpp) en Apple WebKit, como se utiliza en Safari en versiones anteriores a 3.1.1, permite a atacantes remotos ejecutar código arbitrario a través de expresiones regulares con grandes conteos de repetición anidados, lo que desencadena un desbordamiento de búfer basado en memoria dinámica.

CVSS
