| A flaw was found in OpenLDAP. This flaw allows an attacker who can send a malicious packet to be processed by OpenLDAP’s slapd server, to trigger an assertion failure. The highest threat from this vulnerability is to system availability. | |||||
| CVE-2019-9518 | 11 Apache, Apple, Canonical and 8 more | 20 Traffic Server, Mac Os X, Swiftnio and 17 more | 2024-11-21 | 7.8 HIGH | 7.5 HIGH |
| Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU. | |||||
| CVE-2019-9517 | 12 Apache, Apple, Canonical and 9 more | 25 Http Server, Traffic Server, Mac Os X and 22 more | 2024-11-21 | 7.8 HIGH | 7.5 HIGH |
| 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. | |||||
| CVE-2019-9516 | 12 Apache, Apple, Canonical and 9 more | 21 Traffic Server, Mac Os X, Swiftnio and 18 more | 2024-11-21 | 6.8 MEDIUM | 6.5 MEDIUM |
| Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory. | |||||
| CVE-2019-9515 | 12 Apache, Apple, Canonical and 9 more | 24 Traffic Server, Mac Os X, Swiftnio and 21 more | 2024-11-21 | 7.8 HIGH | 7.5 HIGH |
| Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. | |||||
| CVE-2019-9514 | 13 Apache, Apple, Canonical and 10 more | 30 Traffic Server, Mac Os X, Swiftnio and 27 more | 2024-11-21 | 7.8 HIGH | 7.5 HIGH |
| Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both. | |||||
| CVE-2019-9513 | 12 Apache, Apple, Canonical and 9 more | 22 Traffic Server, Mac Os X, Swiftnio and 19 more | 2024-11-21 | 7.8 HIGH | 7.5 HIGH |
| Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU. | |||||
| CVE-2019-9511 | 12 Apache, Apple, Canonical and 9 more | 22 Traffic Server, Mac Os X, Swiftnio and 19 more | 2024-11-21 | 7.8 HIGH | 7.5 HIGH |
| Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. | |||||
| CVE-2019-0211 | 8 Apache, Canonical, Debian and 5 more | 27 Http Server, Ubuntu Linux, Debian Linux and 24 more | 2024-11-21 | 7.2 HIGH | 7.8 HIGH |
| 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. | |||||
| CVE-2019-0197 | 6 Apache, Canonical, Fedoraproject and 3 more | 12 Http Server, Ubuntu Linux, Fedora and 9 more | 2024-11-21 | 4.9 MEDIUM | 4.2 MEDIUM |
| 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. | |||||
| CVE-2018-1333 | 4 Apache, Canonical, Netapp and 1 more | 6 Http Server, Ubuntu Linux, Cloud Backup and 3 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| 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). | |||||
| CVE-2018-1312 | 5 Apache, Canonical, Debian and 2 more | 14 Http Server, Ubuntu Linux, Debian Linux and 11 more | 2024-11-21 | 6.8 MEDIUM | 9.8 CRITICAL |
| 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. | |||||
| CVE-2018-17189 | 7 Apache, Canonical, Debian and 4 more | 13 Http Server, Ubuntu Linux, Debian Linux and 10 more | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| 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. | |||||
