    It was discovered that openNDS did not correctly handle certain memory operations. An attacker could
    possibly use this issue to cause a denial of service or execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
