Descriptions

Heap-based buffer overflow in Perl-Compatible Regular Expression (PCRE) library before 7.3 allows context-dependent attackers to execute arbitrary code via a singleton Unicode sequence in a character class in a regex pattern, which is incorrectly optimized.

Desbordamiento de búfer basado en montículo en la librería Perl-Compatible Regular Expression (PCRE) anterior a 7.3 permite a atacantes locales o remotos (dependiendo del contexto) ejecutar código de su elección mediante una secuencia de caracteres Unicode unitarios en una clase character de un patrón de expresión regular, lo cual está optimizado incorrectamente.
