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.
