"Added an update that fixes a bug trigged by a bogus content-length
header. Under special circumstances, it could crash a varnishd
subthread.

New upstream release. A bugfix release.

Highlights from the changelog :

  - 26 reported bugs fixed.

    - Replaced objects are now expired immediately, instead
      of kept around until expiry.

    - Memory usage on chunked backend responses is lower

Fore a detailed list of changes, please see the project's announcement
at https://www.varnish-cache.org/content/varnish-cache-403

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
