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

Vulnerability Assessment Summary
TCPDump: Decoding routines Denial of Service vulnerability

Detailed Explanation for this Vulnerability Assessment
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 (CVE-2005-1278), BGP
(CVE-2005-1267, CVE-2005-1279), LDP (CVE-2005-1279) and RSVP
(CVE-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.
