AIX 6.1 TL 9 : ntp (IV79942) (deprecated)

Medium Nessus Plugin ID 88055

Synopsis

This plugin has been deprecated.

Description

Network Time Protocol (NTP) is vulnerable to a denial of service, caused by an error in the sntp program. By sending specially crafted NTP packets, a remote attacker from within the local network could exploit this vulnerability to cause the application to enter into an infinite loop. Network Time Protocol (NTP) is vulnerable to a denial of service, caused by an error in ntp_crypto.c. An attacker could exploit this vulnerability using a packet containing an extension field with an invalid value for the length of its value field to cause ntpd to crash. Network Time Protocol (NTP) is vulnerable to a denial of service, caused by an error in ntp_crypto.c. An attacker could exploit this vulnerability using a packet containing an extension field with an invalid value for the length of its value field to cause ntpd to crash. Network Time Protocol (NTP) could allow a remote attacker to obtain sensitive information, caused by a memory leak in CRYPTO_ASSOC. An attacker could exploit this vulnerability to obtain sensitive information. Network Time Protocol (NTP) is vulnerable to a denial of service, caused by an error in ntp_crypto.c. An attacker could exploit this vulnerability using a packet containing an extension field with an invalid value for the length of its value field to cause ntpd to crash. Network Time Protocol (NTP) is vulnerable to a denial of service, caused by an error in the remote configuration functionality. By sending a specially crafted configuration file, an attacker could exploit this vulnerability to cause the application to enter into an infinite loop. Network Time Protocol (NTP) is vulnerable to a buffer overflow, caused by improper bounds checking by the refclock of ntpd. By sending an overly long string, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
Network Time Protocol (NTP) is vulnerable to a denial of service, caused by ASSERT botch instead of returning FAIL on some invalid values by the decodenetnum() function. An attacker could exploit this vulnerability to cause a denial of service.

This plugin has been deprecated to better accommodate iFix supersedence with replacement plugin aix_ntp_v3_advisory4.nasl (plugin id 102321).
