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" References ========== [ 1 ] CVE-2007-1543 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1543 [ 2 ] CVE-2007-1544 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1544 [ 3 ] CVE-2007-1545 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1545 [ 4 ] CVE-2007-1546 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1546 [ 5 ] CVE-2007-1547 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1547 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200704-20.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
