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