Descriptions

Off-by-one error in the convert_query_hexchar function in html.c in cgit.cgi in cgit before 0.8.3.5 allows remote attackers to cause a denial of service (infinite loop) via a string composed of a % (percent) character followed by invalid hex characters, as demonstrated by a %gg sequence.

Error de superación de límite (off-by-one) en la función convert_query_hexchar en html.c en cgit.cgi en cgit anteriores a v0.8.3.5, permite a atacantes remotos provocar una denegación de servicio (buble infinito) a través de una cadena compuesta por un caracter "%" (por ciento) seguido de caracteres hexadecimales no válidos, como se demostró con la secuencia %gg.
