affected by a vulnerability as referenced in the USN-6448-1 advisory.

    Xu Biang discovered that Sofia-SIP did not properly manage memory when handling STUN packets. An attacker
    could use this issue to cause Sofia-SIP to crash, resulting in a denial of service, or possibly 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
number.");
