  1. 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.

  2. 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.

  3. ALPINE-CVE-2019-0196

    Mittel · CVSS 5.3Korrektur verfügbar

    ALPINE-CVE-2019-0196

    A vulnerability was found in Apache HTTP Server 2.4.17 to 2.4.38. Using fuzzed network input, the http/2 request handling could be made to access freed memory in string comparison when determining the method of a request and thus process the request incorrectly.

  4. ALPINE-CVE-2019-0220

    Mittel · CVSS 5.3Korrektur verfügbar

    ALPINE-CVE-2019-0220

    A vulnerability was found in Apache HTTP Server 2.4.0 to 2.4.38. When the path component of a request URL contains multiple consecutive slashes ('/'), directives such as LocationMatch and RewriteRule must account for duplicates in regular expressions while other aspects of the servers processing will implicitly collapse them.

  5. ALPINE-CVE-2019-0211

    Hoch · CVSS 7.8Korrektur verfügbar

    ALPINE-CVE-2019-0211

    In Apache HTTP Server 2.4 releases 2.4.17 to 2.4.38, with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute arbitrary code with the privileges of the parent process (usually root) by manipulating the scoreboard. Non-Unix systems are not affected.

  6. ALPINE-CVE-2019-0217

    Hoch · CVSS 7.5Korrektur verfügbar

    ALPINE-CVE-2019-0217

    In Apache HTTP Server 2.4 release 2.4.38 and prior, a race condition in mod_auth_digest when running in a threaded server could allow a user with valid credentials to authenticate using another username, bypassing configured access control restrictions.

    ALPINE-CVE-2019-0215

    In Apache HTTP Server 2.4 releases 2.4.37 and 2.4.38, a bug in mod_ssl when using per-location client certificate verification with TLSv1.3 allowed a client to bypass configured access control restrictions.

  8. ALPINE-CVE-2019-0190

    Hoch · CVSS 7.5Korrektur verfügbar

    ALPINE-CVE-2019-0190

    A bug exists in the way mod_ssl handled client renegotiations. A remote attacker could send a carefully crafted request that would cause mod_ssl to enter a loop leading to a denial of service. This bug can be only triggered with Apache HTTP Server version 2.4.37 when using OpenSSL version 1.1.1 or later, due to an interaction in changes to handling of renegotiation attempts.

  9. ALPINE-CVE-2018-17199

    Hoch · CVSS 7.5Korrektur verfügbar

    ALPINE-CVE-2018-17199

    In Apache HTTP Server 2.4 release 2.4.37 and prior, mod_session checks the session expiry time before decoding the session. This causes session expiry time to be ignored for mod_session_cookie sessions since the expiry time is loaded when the session is decoded.

    Mittel · CVSS 5.3Korrektur verfügbar

    ALPINE-CVE-2018-17189

    In Apache HTTP server versions 2.4.37 and prior, by sending request bodies in a slow loris way to plain resources, the h2 stream for that request unnecessarily occupied a server thread cleaning up that incoming data. This affects only HTTP/2 (mod_http2) connections.

  11. ALPINE-CVE-2018-11763

    Mittel · CVSS 5.9Korrektur verfügbar

    ALPINE-CVE-2018-11763

    In Apache HTTP Server 2.4.17 to 2.4.34, by sending continuous, large SETTINGS frames a client can occupy a connection, server thread and CPU time without any connection timeout coming to effect. This affects only HTTP/2 connections. A possible mitigation is to not enable the h2 protocol.

    Hoch · CVSS 7.5Korrektur verfügbar

    ALPINE-CVE-2018-8011

    By specially crafting HTTP requests, the mod_md challenge handler would dereference a NULL pointer and cause the child process to segfault. This could be used to DoS the server. Fixed in Apache HTTP Server 2.4.34 (Affected 2.4.33).

    ALPINE-CVE-2018-1333

    By specially crafting HTTP/2 requests, workers would be allocated 60 seconds longer than necessary, leading to worker exhaustion and a denial of service. Fixed in Apache HTTP Server 2.4.34 (Affected 2.4.18-2.4.30,2.4.33).

    Kritisch · CVSS 9.8Korrektur verfügbar

    ALPINE-CVE-2018-1312

    In Apache httpd 2.2.0 to 2.4.29, when generating an HTTP Digest authentication challenge, the nonce sent to prevent reply attacks was not correctly generated using a pseudo-random seed. In a cluster of servers using a common Digest authentication configuration, HTTP requests could be replayed across servers by an attacker without detection.

  15. ALPINE-CVE-2018-1303

    Hoch · CVSS 7.5Korrektur verfügbar

    ALPINE-CVE-2018-1303

    A specially crafted HTTP request header could have crashed the Apache HTTP Server prior to version 2.4.30 due to an out of bound read while preparing data to be cached in shared memory. It could be used as a Denial of Service attack against users of mod_cache_socache. The vulnerability is considered as low risk since mod_cache_socache is not widely used, mod_cache_disk is not concerned by this vulnerability.

  16. ALPINE-CVE-2018-1302

    Mittel · CVSS 5.9Korrektur verfügbar

    ALPINE-CVE-2018-1302

    When an HTTP/2 stream was destroyed after being handled, the Apache HTTP Server prior to version 2.4.30 could have written a NULL pointer potentially to an already freed memory. The memory pools maintained by the server make this vulnerability hard to trigger in usual configurations, the reporter and the team could not reproduce it outside debug builds, so it is classified as low risk.

  17. ALPINE-CVE-2018-1301

    Mittel · CVSS 5.9Korrektur verfügbar

    ALPINE-CVE-2018-1301

    A specially crafted request could have crashed the Apache HTTP Server prior to version 2.4.30, due to an out of bound access after a size limit is reached by reading the HTTP header. This vulnerability is considered very hard if not impossible to trigger in non-debug mode (both log and build level), so it is classified as low risk for common server usage.

  18. ALPINE-CVE-2018-1283

    Mittel · CVSS 5.3Korrektur verfügbar

    ALPINE-CVE-2018-1283

    In Apache httpd 2.4.0 to 2.4.29, when mod_session is configured to forward its session data to CGI applications (SessionEnv on, not the default), a remote user may influence their content by using a "Session" header. This comes from the "HTTP_SESSION" variable name used by mod_session to forward its data to CGIs, since the prefix "HTTP_" is also used by the Apache HTTP Server to pass HTTP header fields, per CGI specifications.

  19. ALPINE-CVE-2017-15715

    Hoch · CVSS 8.1Korrektur verfügbar

    ALPINE-CVE-2017-15715

    In Apache httpd 2.4.0 to 2.4.29, the expression specified in <FilesMatch> could match '$' to a newline character in a malicious filename, rather than matching only the end of the filename. This could be exploited in environments where uploads of some files are are externally blocked, but only by matching the trailing portion of the filename.

  20. ALPINE-CVE-2017-15710

    Hoch · CVSS 7.5Korrektur verfügbar

    ALPINE-CVE-2017-15710

    In Apache httpd 2.0.23 to 2.0.65, 2.2.0 to 2.2.34, and 2.4.0 to 2.4.29, mod_authnz_ldap, if configured with AuthLDAPCharsetConfig, uses the Accept-Language header value to lookup the right charset encoding when verifying the user's credentials. If the header value is not present in the charset conversion table, a fallback mechanism is used to truncate it to a two characters value to allow a quick retry (for example, 'en-US' is truncated to 'en'). A header value of less than two characters forces an out of bound write of one NUL byte to a memory location that is not part of the string. In the worst case, quite unlikely, the process would crash
