Unknown vulnerability in tcpdump before 3.7.2 related to an inability to "Handle unknown RADIUS attributes properly," allows remote attackers to cause a denial of service (infinite loop), a different vulnerability than CAN-2003-0093.

isakmpsubprint in tcpdump 3.6 through 3.7.1 allows remote attackers to cause a denial of service (CPU consumption) via a certain malformed ISAKMP packet to UDP port 500, which causes tcpdump to enter an infinite loop.

The L2TP protocol parser in tcpdump 3.8.1 and earlier allows remote attackers to cause a denial of service (infinite loop and memory consumption) via a packet with invalid data to UDP port 1701, which causes l2tpavpprint to use a bad length value when calling printoctets.

The printattrstring function in print-radius.c for tcpdump 3.8.1 and earlier allows remote attackers to cause a denial of service (segmentation fault) via a RADIUS attribute with a large length value.

The bgpupdateprint function in tcpdump 3.x does not properly handle a -1 return value from the decodeprefix4 function, which allows remote attackers to cause a denial of service (infinite loop) via a crafted BGP packet.
