Synopsis ========
The Network Audio System is vulnerable to a buffer overflow that could result in the execution of arbitrary code with root privileges.
Background ==========
NAS is a network transparent, client/server audio transport system.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/nas < 1.8b >= 1.8b
Description ===========
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.
Resolution ==========
All NAS users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/nas-1.8b"
