Debian LTS Advisory DLA-2920-1 [email protected]

Package : varnish
Version : 5.0.0-7+deb9u3
CVE ID : CVE-2022-23959
Debian Bug : 1004433
James Kettle discovered that a request smuggling attack can be performed on
HTTP/1 connections on Varnish servers, high-performance web accelerators. The
smuggled request would be treated as an additional request by the Varnish
server which may lead to information disclosure and cache poisoning.
For Debian 9 stretch, this problem has been fixed in version
5.0.0-7+deb9u3.
We recommend that you upgrade your varnish packages.
For the detailed security status of varnish please refer to
its security tracker page at:
