  1. ALPINE-CVE-2021-31618

    Hoch · CVSS 7.5Korrektur verfügbar

    ALPINE-CVE-2021-31618

    Apache HTTP Server protocol handler for the HTTP/2 protocol checks received request headers against the size limitations as configured for the server and used for the HTTP/1 protocol as well. On violation of these restrictions and HTTP response is sent to the client with a status code indicating why the request was rejected. This rejection response was not fully initialised in the HTTP/2 protocol handler if the offending header was the very first one received or appeared in a a footer. This led to a NULL pointer dereference on initialised memory, crashing reliably the child process. Since such a triggering HTTP/2 request is easy to craft and

  5. ALPINE-CVE-2020-35452

    Hoch · CVSS 7.3Korrektur verfügbar

    ALPINE-CVE-2020-35452

    Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Digest nonce can cause a stack overflow in mod_auth_digest. There is no report of this overflow being exploitable, nor the Apache HTTP Server team could create one, though some particular compiler and/or compilation option might make it possible, with limited consequences anyway due to the size (a single byte) and the value (zero byte) of the overflow

    ALPINE-CVE-2020-13950

    Apache HTTP Server versions 2.4.41 to 2.4.46 mod_proxy_http can be made to crash (NULL pointer dereference) with specially crafted requests using both Content-Length and Transfer-Encoding headers, leading to a Denial of Service

  8. ALPINE-CVE-2020-9490

    Hoch · CVSS 7.5Korrektur verfügbar

    ALPINE-CVE-2020-9490

    Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers.

  9. ALPINE-CVE-2020-11993

    Hoch · CVSS 7.5Korrektur verfügbar

    ALPINE-CVE-2020-11993

    Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above "info" will mitigate this vulnerability for unpatched servers.

    ALPINE-CVE-2019-17657

    An Uncontrolled Resource Consumption vulnerability in Fortinet FortiSwitch below 3.6.11, 6.0.6 and 6.2.2, FortiAnalyzer below 6.2.3, FortiManager below 6.2.3 and FortiAP-S/W2 below 6.2.2 may allow an attacker to cause admin webUI denial of service (DoS) via handling special crafted HTTP requests/responses in pieces slowly, as demonstrated by Slow HTTP DoS Attacks.

    ALPINE-CVE-2020-1927

    In Apache HTTP Server 2.4.0 to 2.4.41, redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an an unexpected URL within the request URL.

    ALPINE-CVE-2019-10097

    In Apache HTTP Server 2.4.32-2.4.39, when mod_remoteip was configured to use a trusted intermediary proxy server using the "PROXY" protocol, a specially crafted PROXY header could trigger a stack buffer overflow or NULL pointer deference. This vulnerability could only be triggered by a trusted proxy and not by untrusted HTTP clients.

    ALPINE-CVE-2019-10092

    In Apache HTTP Server 2.4.0-2.4.39, a limited cross-site scripting issue was reported affecting the mod_proxy error page. An attacker could cause the link on the error page to be malformed and instead point to a page of their choice. This would only be exploitable where a server was set up with proxying enabled but was misconfigured in such a way that the Proxy Error page was displayed.

    ALPINE-CVE-2019-10081

    HTTP/2 (2.4.20 through 2.4.39) very early pushes, for example configured with "H2PushResource", could lead to an overwrite of memory in the pushing request's pool, leading to crashes. The memory copied is that of the configured push link header values, not data supplied by the client.

  19. ALPINE-CVE-2019-9517

    Hoch · CVSS 7.5Korrektur verfügbar

    ALPINE-CVE-2019-9517

    Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both.

  20. ALPINE-CVE-2019-0197

    Mittel · CVSS 4.2Korrektur verfügbar

    ALPINE-CVE-2019-0197

    A vulnerability was found in Apache HTTP Server 2.4.34 to 2.4.38. When HTTP/2 was enabled for a http: host or H2Upgrade was enabled for h2 on a https: host, an Upgrade request from http/1.1 to http/2 that was not the first request on a connection could lead to a misconfiguration and crash. Server that never enabled the h2 protocol or that only enabled it for https: and did not set "H2Upgrade on" are unaffected by this issue.
