                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.


Please verify the update prior to upgrading to ensure the integrity of
the downloaded package.  You can do this with the command:
  rpm --checksig package.rpm
You can get the GPG public key of the Mandrake Linux Security Team at
If you use MandrakeUpdate, the verification of md5 checksum and GPG
signature is performed automatically for you.
