The remote host is affected by the vulnerability described in GLSA-200505-06 (TCPDump: Decoding routines Denial of Service vulnerability)
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.
Impact :
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.
Workaround :
There is no known workaround at this time.
