Descriptions

Heap-based buffer overflow in PCRE 8.36 and earlier allows remote attackers to cause a denial of service (crash) or have other unspecified impact via a crafted regular expression, related to an assertion that allows zero repeats.

Desbordamiento de buffer basado en memoria dinámica en PCRE 8.36 y anteriores permite a atacantes remotos causar una denegación de servicio (caída) o tener otro impacto no especificado a través de una expresión regular manipulada, relacionado con una aserción que permite cero repeticiones.

A flaw was found in the way PCRE handled certain malformed regular expressions. This issue could cause an application (for example, Konqueror) linked against PCRE to crash while parsing malicious regular expressions.
