From: Damon Morda <dgm@cert.org> To: conectiva-updates@papaleguas.conectiva.com.br, linuxlist@securityportal.com, lwn@lwn.net, cert@cert.org Subject: [CLA-2001:403] Conectiva Linux Security Announcement - fetchmail VU#739739 Date: Tue, 19 Jun 2001 11:45:23 -0400 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- 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!
