Hamid Zamani discovered multiple security issues in the Network Audio System (NAS) server. An attacker could possibly use these issues to cause a denial of service or execute arbitrary code. (CVE-2013-4256, CVE-2013-4257).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
