The remote host is missing updates announced in advisory CLA-2005:913.
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: The apt tool can be used to perform RPM package upgrades by running 'apt-get update' followed by 'apt-get upgrade'
