NVD Description

Note: Versions mentioned in the description apply only to the upstream varnish-devel package and not the varnish-devel package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

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.
