GLSA-200712-10 : Samba: Execution of arbitrary code

High Nessus Plugin ID 29297

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200712-10 (Samba: Execution of arbitrary code)

Alin Rad Pop (Secunia Research) discovered a boundary checking error in the send_mailslot() function which could lead to a stack-based buffer overflow.
Impact :

A remote attacker could send a specially crafted 'SAMLOGON' domain logon packet, possibly leading to the execution of arbitrary code with elevated privileges. Note that this vulnerability is exploitable only when domain logon support is enabled in Samba, which is not the case in Gentoo's default configuration.
Workaround :

Disable domain logon in Samba by setting 'domain logons = no' in the 'global' section of your smb.conf and restart Samba.

Solution

All Samba users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-fs/samba-3.0.28'
