CVE-2019-20637

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.
