Discussion

tcpdump BGP 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 Border Gateway Protocol (BGP) packets. A remote attacker may send malformed BGP packets to cause the software to enter an infinite loop and hang.
