Date: Thu, 25 Nov 2004 13:04:42 -0200 From: Conectiva Updates <secure@...ectiva.com.br> To: conectiva-updates@...aleguas.conectiva.com.br, lwn@....net, bugtraq@...urityfocus.com, security-alerts@...uxsecurity.com, linsec@...ts.seifried.org Subject: [CLA-2004:899] Conectiva Security Announcement - samba -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : samba SUMMARY : Fix for Samba's denial of service vulnerability DATE : 2004-11-25 13:03:00 ID : CLA-2004:899 RELEVANT RELEASES : 10 - ------------------------------------------------------------------------- DESCRIPTION Samba[1] provides SMB/CIFS services (such as file and printer sharing) used by clients compatible with Microsoft Windows(TM). Karol Wiesek found a vulnerability[2] in the input validation routines in Samba 3.x used to match filename strings containing wildcard characters that may allow a remote attacker to consume abnormal amounts of CPU cycles. Also, Steffan Esser found a buffer overflow in the QFILEPATHINFO request handler in Samba 3.0.x through 3.0.7 that may allow remote attackers to execute arbitrary code via a TRANSACT2_QFILEPATHINFO request with a small "maximum data bytes" value. SOLUTION It is recommended that all Samba users upgrade their packages. This update will automatically restart the service if it is already running.
