-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : tcpdump SUMMARY : Buffer Overflow when parsing NFS traffic DATE : 2002-06-05 13:53:00 ID : CLA-2002:491 RELEVANT RELEASES : 6.0, 7.0, 8 - ------------------------------------------------------------------------- DESCRIPTION Tcpdump is a command-line tool for monitoring network traffic. David Woodhouse <dwmw2at_private> discovered[1] a buffer overflow vulnerability in tcpdump when it is parsing NFS traffic. A remote attacker could exploit this to at least crash the tcpdump process. Even though arpwatch and libpcap are not affected by this vulnerability, new packages for them are being provided for Conectiva Linux 6.0 and 7.0 since they are generated together with tcpdump from the same SRPM package. SOLUTION All tcpdump users should upgrade.
