    PACKAGE : samba
    SUMMARY : Fix for Samba's denial of service vulnerability
    DATE : 2004-11-25 13:03:00
    ID : CLA-2004:899

    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.
