The remote Ubuntu 18.04 LTS / 20.04 LTS / 21.10 / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5474-1 advisory.

  - An issue was discovered in Varnish Cache before 6.0.5 LTS, 6.1.x and 6.2.x before 6.2.2, and 6.3.x before     6.3.1. It does not clear a pointer between the handling of one client request and the next request within     the same connection. This sometimes causes information to be disclosed from the connection workspace, such     as data structures associated with previous requests within this connection or VCL-related temporary     headers.

  - An issue was discovered in Varnish Cache before 6.0.6 LTS, 6.1.x and 6.2.x before 6.2.3, and 6.3.x before     6.3.2.
