Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4814-1 advisory.

 Alex Villacis Lasso discovered that Asterisk did not properly check the length of input string when setting the user field for PartyA on a CDR. A remote attacker could use this vulnerability to cause a denial of service (crash) or potentially execute arbitrary code. (CVE-2017-7617)
