Description:
Rapid7 has discovered two vulnerabilities in TCPDUMP, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerabilities are caused due to errors within the ISAKMP payload handling and may crash TCPDUMP when receiving a packet one of the following specially crafted payloads:
1) An ISAKMP packet with a "Delete" payload that includes a large number of SPIs (Security Parameter Indexes).
2) An ISAKMP packet with an "Identification" payload with a value in the "Payload Length" field that becomes less than 8 bytes when the byte order is reversed.
Successful exploitation requires that the "-v" command line option is used.
The vulnerabilities affect version 3.8.1 and prior.
Solution:
Update to version 3.8.2 or 3.8.3.
