Descriptions
The compile_bracket_matchingpath function in pcre_jit_compile.c in PCRE through 8.x before revision 1680 (e.g., the PHP 7.1.1 bundled version) allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted regular expression.
La función compile_bracket_matchingpath en pcre_jit_compile.c en PCRE hasta la versión 8.x en versiones anteriores a la revisión 1680 (por ejemplo, la versión empacada de PHP 7.1.1) permite a atacantes remotos provocar una denegación de servicio (lectura fuera de límites y caída de la aplicación) a través de una expresión regular manipulada.
