-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : samba SUMMARY : Fixes for Samba vulnerabilities DATE : 2005-01-06 17:10:00 ID : CLA-2005:913 RELEVANT RELEASES : 9, 10 - ------------------------------------------------------------------------- DESCRIPTION Samba[1] provides SMB/CIFS services (such as file and printer sharing) used by clients compatible with Microsoft Windows(TM). Remote exploitation of an integer overflow vulnerability[2] in the smbd daemon could allow an attacker to cause controllable heap corruption, leading to execution of arbitrary commands with root privileges. In order to exploit this vulnerability an attacker must possess credentials that allow access to a share on the Samba server. Unsuccessful exploitation attempts will cause the process serving the request to crash with signal 11, and may leave evidence of an attack in logs. SOLUTION It is recommended that all Samba users upgrade their packages. This update will automatically restart the service if it is already running.
