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
