GLSA-200704-20 : NAS: Multiple vulnerabilities

critical Nessus Plugin ID 25108

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-200704-20 (NAS: Multiple vulnerabilities)

 Luigi Auriemma has discovered multiple vulnerabilities in NAS, some of which include a buffer overflow in the function accept_att_local(), an integer overflow in the function ProcAuWriteElement(), and a null pointer error in the function ReadRequestFromClient().
 Impact :

 An attacker having access to the NAS daemon could send an overly long slave name to the server, leading to the execution of arbitrary code with root privileges. A remote attacker could also send a specially crafted packet containing an invalid client ID, which would crash the server and result in a Denial of Service.
 Workaround :

 There is no known workaround at this time.

Solution

All NAS users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/nas-1.8b'
