-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : samba SUMMARY : Multiple potential buffer overruns DATE : 2004-07-30 11:35:00 ID : CLA-2004:854 RELEVANT RELEASES : 8, 9 - ------------------------------------------------------------------------- DESCRIPTION Samba[1] provides SMB/CIFS services (such as file and printer sharing) used by clients compatible with Microsoft Windows(TM). Evgeny Demidov noticed that the internal routine used by the Samba Web Administration Tool (SWAT) to decode the base64 data during HTTP basic authentication is subject[2] to a buffer overrun caused by an invalid base64 character. This same code is used internally to decode the sambaMungedDial attribute value when using the ldapsam passdb backend and to decode input given to the ntlm_auth tool. Another buffer overrun problem[3] has been located in the code used to support the 'mangling method = hash' smb.conf option. Please be aware that the default setting for this parameter is 'mangling method = hash2' and therefore not vulnerable. SOLUTION It is recommended that all samba users upgrade their packages. This update will automatically restart the service if it is already running.
