                Mandrake Linux Security Update Advisory

Package name:           fetchmail
Date:                   July 5th, 2001
Advisory ID:            MDKSA-2001:063

Affected versions:      7.1, 7.2, 8.0, Corporate Server 1.0.1,
                        Single Network Firewall 7.2

Problem Description:

 Wolfram Kleff reported recently that the fetchmail program would
 segfault when receiving emails with a very large "To:" header.  This is
 due to a buffer overflow within the header parsing code, which can be
 exploited remotely.
