 Mandriva Linux Security Advisory                         MDKSA-2007:105
 http://www.mandriva.com/security/
 _______________________________________________________________________
 
 Package : fetchmail
 Date    : May 17, 2007
 Affected: 2007.0, 2007.1, Corporate 3.0, Corporate 4.0
 _______________________________________________________________________
 
 Problem Description:
 
 The APOP functionality in fetchmail's POP3 client implementation was
 validating the APOP challenge too lightly, accepting random garbage
 as a POP3 server's APOP challenge, rather than insisting it conform
 to RFC-822 specifications.
 
 As a result of this flaw, it made man-in-the-middle attacks easier than
 necessary to retrieve the first few characters of the APOP secret,
 allowing them to potentially brute force the remaining characters
 easier than should be possible.
 
 Updated packages have been patched to prevent these issues, however it
 should be noted that the APOP MD5-based authentication scheme should
 no longer be considered secure.
