Description

The remote host is affected by the vulnerability described in GLSA-200705-15 (Samba: Multiple vulnerabilities)

Samba contains a logical error in the smbd daemon when translating     local SID to user names (CVE-2007-2444). Furthermore, Samba contains     several bugs when parsing NDR encoded RPC parameters (CVE-2007-2446).
Lastly, Samba fails to properly sanitize remote procedure input     provided via Microsoft Remote Procedure Calls (CVE-2007-2447).

Impact :

A remote attacker could exploit these vulnerabilities to gain root     privileges via various vectors.

Workaround :

There is no known workaround at this time.
