GLSA-200505-06 : TCPDump: Decoding routines Denial of Service vulnerability

medium Nessus Plugin ID 18232

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

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.

Solution

All TCPDump users should upgrade to the latest available version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-analyzer/tcpdump-3.8.3-r3'
