Descriptions

Perl-Compatible Regular Expression (PCRE) library before 7.3 backtracks too far when matching certain input bytes against some regex patterns in non-UTF-8 mode, which allows context-dependent attackers to obtain sensitive information or cause a denial of service (crash), as demonstrated by the "\X?\d" and "\P{L}?\d" patterns.

La librería Perl-Compatible Regular Expression (PCRE) anterior a 7.3 vuelve demasiado atrás cuando compara determinados bytes de entrada con algunos patrones de expresiones regulares en modo no-UTF-8, lo cual permite a atacantes locales o remotos (dependiendo del contexto) obtener información sensible o provocar una denegación de servicio (caída), como se ha demostrado mediante los patrones "\X?\d" y "\P{L}?\d".
