Descriptions

Stack-based buffer overflow in the crypto_recv function in ntp_crypto.c in ntpd in NTP before 4.2.4p7 and 4.2.5 before 4.2.5p74, when OpenSSL and autokey are enabled, allows remote attackers to execute arbitrary code via a crafted packet containing an extension field.

Desbordamiento de búfer basado en pila en la función crypto_recv en ntp_crypto.c en ntpd en NTP anteriores a v4.2.4p7 y v4.2.5 anterior a v4.2.5p74, cuando OpenSSL y autokey están activados, permite a atacantes remotos ejecutar código de forma arbitraria a través de paquetes manipulados que contienen un campo de extension.
