Descriptions

Stack-based buffer overflow in the Curl_sasl_create_digest_md5_message function in lib/curl_sasl.c in curl and libcurl 7.26.0 through 7.28.1, when negotiating SASL DIGEST-MD5 authentication, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long string in the realm parameter in a (1) POP3, (2) SMTP or (3) IMAP message.

Desbordamiento de búfer basado en pila en la función de curl_sasl_create_digest_md5_message de libcurl en lib/curl_sasl.c v7.26.0 hasta v7.28.1 a durante la negociación de la autenticación SASL DIGEST-MD5, lo que permite a atacantes remotos provocar una denegación de servicio (caída de la aplicación) y posiblemente ejecutar código de su elección a través de una cadena demasiado larga en el parámetro 'realm' en un mensaje (1) POP3, (2) SMTP o (3) IMAP.
