Descriptions
The (1) S_reghop3, (2) S_reghop4, and (3) S_reghopmaybe3 functions in regexec.c in Perl before 5.24.0 allow context-dependent attackers to cause a denial of service (infinite loop) via crafted utf-8 data, as demonstrated by "a\x80."
Las funciones (1) S_reghop3, (2) S_reghop4 y (3) S_reghopmaybe3 en regexec.c en Perl en versiones anteriores a 5.24.0 permiten a atacantes dependientes del contexto provocar una denegación de servicio (bucle infinito) a través de datos utf-8 manipulados, según lo demostrado por "a\x80".
