SUMMARY   : Remote buffer overflow vulnerability
DATE      : 2001-06-19 10:47:00
ID        : CLA-2001:403

RELEASES  : 4.0, 4.0es, 4.1, 4.2, 5.0, prg graficos, ecommerce, 5.1, 6.0

DESCRIPTION
 "fetchmail" is a program used to retrieve email from POP and IMAP
 servers.
 Wolfram Kleff reported [1] that fetchmail would segfault when
 receiving emails with large "To:" headers. This was due to a buffer
 overflow in the header parser and it could be exploited remotely.


SOLUTION
 It is recommended that all fetchmail users upgrade this package as
 soon as possible.
 
 IMPORTANT: it is necessary to manually restart the fetchmail daemon
 after installing the update!
