                Mandrake Linux Security Update Advisory
______________________________________________________________________

Package name:           bind
Advisory ID:            MDKSA-2002:038
Date:                   June 4th, 2002
Affected versions:      8.0, 8.1, 8.2
______________________________________________________________________

Problem Description:

 A vulnerability was discovered in the BIND9 DNS server in versions
 prior to 9.2.1.  An error condition will trigger the shutdown of the
 server when the rdataset parameter to the dns_message_findtype()
 function in message.c is not NULL as expected.  This condition causes
 the server to assert an error message and shutdown the BIND server.
 The error condition can be remotely exploited by a special DNS packet.
 This can only be used to create a Denial of Service on the server; the
 error condition is correctly detected, so it will not allow an attacker
 to execute arbitrary code on the server.
