TCPDump is a tool for network monitoring and data acquisition.
TCPDump improperly handles and decodes ISIS (CAN-2005-1278), BGP (CAN-2005-1267, CAN-2005-1279), LDP (CAN-2005-1279) and RSVP (CAN-2005-1280) packets. TCPDump might loop endlessly after receiving malformed packets.
A malicious remote attacker can exploit the decoding issues for a Denial of Service attack by sending specially crafted packets, possibly causing TCPDump to loop endlessly.
There is no known workaround at this time.
All TCPDump users should upgrade to the latest available version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/tcpdump-3.8.3-r3"
