AIX 6.1 TL 9 : bos.net.tcp.client (U869149)

High Nessus Plugin ID 91236

Synopsis

The remote AIX host is missing a vendor-supplied security patch.

Description

The remote host is missing AIX PTF U869149, which is related to the security of the package bos.net.tcp.client.

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.

ISC BIND is vulnerable to a denial of service, caused by an error in db.c when parsing incoming responses. A remote attacker could exploit this vulnerability to trigger a REQUIRE assertion failure and cause a denial of service.

ISC BIND is vulnerable to a denial of service, caused by improper bounds checking in apl_42.c. By sending specially crafted Address Prefix List (APL) data, a remote authenticated attacker could exploit this vulnerability to trigger an INSIST assertion failure and cause the named process to terminate.
