medium Nessus Plugin ID 58969

Synopsis

The remote Debian host is missing a security-related update.

Description

Ivano Cristofolini discovered that insufficient security checks in Samba's handling of LSA RPC calls could lead to privilege escalation by gaining the 'take ownership' privilege.

Solution

Upgrade the samba packages.

For the stable distribution (squeeze), this problem has been fixed in version 3.5.6~dfsg-3squeeze8.
