A vulnerability in tcpdump could allow a remote attacker to cause a denial of service on an affected system.
The tcpdump tool allows for the inspection of network packets and contains decoders for many standard protocols, including the Internet Security Association and Key Management Protocol (ISAKMP). The ISAKMP standard specifies:
The Delete Payload contains a protocol-specific security association identifier that the sender has removed from its security association database and is, therefore, no longer valid. [...] It is possible to send multiple Security Parameter Index(es) (SPIs) in a Delete payload [...]
A remote attacker could cause tcpdump to crash.
