Gentoo Linux Security Advisory

Title: Samba: Multiple vulnerabilities (GLSA 200705-15)
Severity: high
Exploitable: remote
Date: May 15, 2007
Bug(s): #177029
ID: 200705-15

Synopsis

Samba contains multiple vulnerabilities potentially resulting in the execution of arbitrary code with root privileges.

Background

Samba is a suite of SMB and CIFS client/server programs for UNIX.

Affected Packages

Package: net-fs/samba
Vulnerable: < 3.0.24-r2
Unaffected: >= 3.0.24-r2
Architectures: All supported architectures


Description

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.

Resolution

All Samba users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-fs/samba-3.0.24-r2"
