Andrew Griffiths and iDEFENSE Labs discovered a problem in tcpdump, a powerful tool for network monitoring and data acquisition. An attacker is able to send a specially crafted network packet which causes tcpdump to enter an infinite loop.
In addition to the above problem the tcpdump developers discovered a potential infinite loop when parsing malformed BGP packets. They also discovered a buffer overflow that can be exploited with certain malformed NFS packets.
