                Mandrake Linux Security Update Advisory
______________________________________________________________________

Package name:           tcpdump
Advisory ID:            MDKSA-2003:027
Date:                   March 3rd, 2003

Affected versions:      8.1, 8.2, 9.0, Corporate Server 2.1,
                        Multi Network Firewall 8.2,
                        Single Network Firewall 7.2
______________________________________________________________________

Problem Description:

 A vulnerability was discovered by Andrew Griffiths and iDEFENSE Labs
 in the tcpdump program.  By sending a specially crafted network packet,
 an attacker is able to to cause tcpdump to enter an infinite loop.  In
 addition, the tcpdump developers found a potential infinite loop when
 tcpdump parses malformed BGP packets.  A buffer overflow was also
 discovered that can be exploited with certain malformed NFS packets.
