Descriptions
Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Digest nonce can cause a stack overflow in mod_auth_digest. There is no report of this overflow being exploitable, nor the Apache HTTP Server team could create one, though some particular compiler and/or compilation option might make it possible, with limited consequences anyway due to the size (a single byte) and the value (zero byte) of the overflow
Apache HTTP Server versiones 2.4.0 a 2.4.46 Un Digest nonce especialmente diseñado puede causar un desbordamiento de pila en la función mod_auth_digest. No existe reportes de que este desbordamiento sea explotable, ni el equipo del Servidor HTTP Apache podría crear uno, aunque algún compilador y/o opción de compilación particular podría hacerlo posible, con consecuencias limitadas de todos modos debido al tamaño (un solo byte) y el valor (cero bytes) del desbordamiento
A flaw was found in Apache httpd. The mod_auth_digest has a single zero byte stack overflow. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
