Description

This update 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.
