CVE-2002-2223

TITLE

Multiple vendors' Internet Key Exchange (IKE) implementations do not properly handle IKE response packets

Trust: 0.8

sources: CERT/CC: VU#287771

DESCRIPTION

Buffer overflow in NetScreen-Remote 8.0 allows remote attackers to cause a denial of service and possibly execute arbitrary code via crafted Internet Key Exchange (IKE) response packets, possibly including (1) a large Security Parameter Index (SPI) field, (2) large number of payloads, or (3) a long payload. Internet Key Exchange (IKE) implementations from several vendors contain buffer overflows and denial-of-service conditions. The buffer overflow vulnerabilities could permit an attacker to execute arbitrary code on a vulnerable system. This is reported to cause the daemon to crash. This issue may be related to the multiple IKE implementation vulnerabilities described in CERT/CC Vulnerability Note VU#287771. Other vendor products are reported to be affected by similar issues. There are currently not enough details available to determine if PGPFreeware is affected by any of these specific issues. This issue was reported in PGPFreeware 7.03 running on Windows NT 4.0 SP6. The Cisco VPN Client is prone to a remotely exploitable buffer overflow condition. It is possible to trigger this condition by sending malformed IKE packets to the client. The overflow occurs when the Security Parameter Index payload of the IKE packet is longer than 16 bytes in length. It is possible that exploitation of this vulnerability may affect availability of the client, resulting in a denial of service condition. This issue is reported to be exploitable when the client software is operating in Aggressive Mode during a phase 1 IKE exchange. This vulnerability affects versions of the client on all platforms. When vulnerable clients receive a specific IKE packet with a zero length payload, the VPN client will consume all available processor time. < *Link: http://www.netscreen.com/support/alerts/9_6_02.htm* >
