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