Synopsis

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

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4059-1 advisory.

 It was discovered that Squid incorrectly handled certain SNMP packets. A remote attacker could possibly use this issue to cause memory consumption, leading to a denial of service. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2018-19132)

 It was discovered that Squid incorrectly handled the cachemgr.cgi web module. A remote attacker could possibly use this issue to conduct cross-site scripting (XSS) attacks. (CVE-2019-13345)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
