Descriptions

Perl-Compatible Regular Expression (PCRE) library before 7.3 does not properly compute the length of (1) a \p sequence, (2) a \P sequence, or (3) a \P{x} sequence, which allows context-dependent attackers to cause a denial of service (infinite loop or crash) or execute arbitrary code.

La librería Perl-Compatible Regular Expression (PCRE) anterior a 7.3 no computa adecuadamente la longitud de (1) una secuencia \p, (2) una secuencia \P, o (3) una secuencia \P{x}, lo cual permite a atacantes dependientes de contexto provocar una denegación de servicio (bucle infinito o caída) o ejecutar código de su elección.
