| CVE-2021-28543 | 2 Fedoraproject, Varnish-cache | 3 Fedora, Varnish-modules, Varnish-modules Klarlack | 2024-11-21 | 5.0 MEDIUM | 4.0 MEDIUM |
| Varnish varnish-modules before 0.17.1 allows remote attackers to cause a denial of service (daemon restart) in some configurations. This does not affect organizations that only install the Varnish Cache product; however, it is common to install both Varnish Cache and varnish-modules. Specifically, an assertion failure or NULL pointer dereference can be triggered in Varnish Cache through the varnish-modules header.append() and header.copy() functions. For some Varnish Configuration Language (VCL) files, this gives remote clients an opportunity to cause a Varnish Cache restart. A restart reduces overall availability and performance due to an increased number of cache misses, and may cause higher load on backend servers. | |||||
