Descriptions

Integer overflow in the PCRE regular expression compiler (JavaScriptCore/pcre/pcre_compile.cpp) in Apple WebKit, as used in Safari before 3.1.1, allows remote attackers to execute arbitrary code via a regular expression with large, nested repetition counts, which triggers a heap-based buffer overflow.

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.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Safari. User interaction is required to exploit this vulnerability in that the target must visit a malicious page.
The specific flaw exists in the regular expression compiler (JavaScriptCore/pcre/pcre_compile.cpp) in WebKit. When nesting regular expressions with large repetitions, a heap overflow occurs resulting in a condition allowing the execution of arbitrary code.
