ID        : CLA-2001:419

DESCRIPTION
 Fetchmail is a program used to retrieve email from POP and IMAP
 servers.
 Salvatore Sanfilippo did an audit and found a remote vulnerability in
 fetchmail that allows a remote attacker to write arbitrary data into
 memory. To take advantage of this problem, an attacker has to have
 control over the mail server being queried by the fetchmail process.


SOLUTION
 All fetchmail users should upgrade.
 
 IMPORTANT: if fetchmail is running as a daemon, it will have to be
 restarted after applying the update in order to run the new version.
