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.
