| CVE-2021-36740 | 5 Debian, Fedoraproject, Varnish-cache and 2 more | 5 Debian Linux, Fedora, Varnish Cache and 2 more | 2024-11-21 | 6.4 MEDIUM | 6.5 MEDIUM |
| Varnish Cache, with HTTP/2 enabled, allows request smuggling and VCL authorization bypass via a large Content-Length header for a POST request. This affects Varnish Enterprise 6.0.x before 6.0.8r3, and Varnish Cache 5.x and 6.x before 6.5.2, 6.6.x before 6.6.1, and 6.0 LTS before 6.0.8. | |||||
| 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. | |||||
| CVE-2020-11653 | 4 Debian, Opensuse, Varnish-cache and 1 more | 5 Debian Linux, Backports Sle, Leap and 2 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Varnish Cache before 6.0.6 LTS, 6.1.x and 6.2.x before 6.2.3, and 6.3.x before 6.3.2. It occurs when communication with a TLS termination proxy uses PROXY version 2. There can be an assertion failure and daemon restart, which causes a performance loss. | |||||
| CVE-2019-20637 | 3 Opensuse, Varnish-cache, Varnish-software | 4 Backports Sle, Leap, Varnish Cache and 1 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
| CVE-2017-8807 | 3 Debian, Varnish-cache, Varnish Cache Project | 3 Debian Linux, Varnish, Varnish Cache | 2024-11-21 | 6.4 MEDIUM | 9.1 CRITICAL |
| vbf_stp_error in bin/varnishd/cache/cache_fetch.c in Varnish HTTP Cache 4.1.x before 4.1.9 and 5.x before 5.2.1 allows remote attackers to obtain sensitive information from process memory because a VFP_GetStorage buffer is larger than intended in certain circumstances involving -sfile Stevedore transient objects. | |||||
| CVE-2017-12425 | 3 Varnish-cache, Varnish-software, Varnish Cache Project | 3 Varnish, Varnish Cache, Varnish Cache | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Varnish HTTP Cache 4.0.1 through 4.0.4, 4.1.0 through 4.1.7, 5.0.0, and 5.1.0 through 5.1.2. A wrong if statement in the varnishd source code means that particular invalid requests from the client can trigger an assert, related to an Integer Overflow. This causes the varnishd worker process to abort and restart, losing the cached contents in the process. An attacker can therefore crash the varnishd worker process on demand and effectively keep it from serving content - a Denial-of-Service attack. The specific source-code filename containing the incorrect statement varies across releases. | |||||
| CVE-2013-4484 | 2 Varnish-cache, Varnish Cache Project | 2 Varnish, Varnish Cache | 2024-11-21 | 5.0 MEDIUM | N/A |
| Varnish before 3.0.5 allows remote attackers to cause a denial of service (child-process crash and temporary caching outage) via a GET request with trailing whitespace characters and no URI. | |||||
