Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-5104-1 advisory.

 Lyu discovered that Squid incorrectly handled WCCP protocol data. A remote attacker could use this issue to cause Squid to crash, resulting in a denial of service, or possibly obtain sensitive information.

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.
