                Mandrake Linux Security Update Advisory
________________________________________________________________________

Package name:           fetchmail
Advisory ID:            MDKSA-2002:036
Date:                   May 28th, 2002
Affected versions:      7.1, 7.2, 8.0, 8.1, 8.2, Corporate Server 1.0.1
                        Single Network Firewall 7.2
________________________________________________________________________

Problem Description:

 A problem was discovered with versions of fetchmail prior to 5.9.10
 that was triggered by retreiving mail from an IMAP server.  The
 fetchmail client will allocate an array to store the sizes of the
 messages it is attempting to retrieve.  This array size is determined
 by the number of messages the server is claiming to have, and fetchmail
 would not check whether or not the number of messages the server was
 claiming was too high.  This would allow a malicious server to make the
 fetchmail process write data outside of the array bounds.
