tcpdump LDP Decoding Routines Denial Of Service Vulnerability

The 'tcpdump' utility is prone to a vulnerability that may allow a remote attacker to cause a denial-of-service condition in the software. The issue occurs because of the way tcpdump decodes Label Distribution Protocol (LDP) datagrams. A remote attacker may send malformed LDP datagrams to cause the software to enter an infinite loop and hang.

This issue affects tcpdump 3.8.3 and earlier.
