| CVE-2023-44487 | 31 Akka, Amazon, Apache and 28 more | 127 Http Server, Opensearch Data Prepper, Apisix and 124 more | 2023-12-20 | N/A | 7.5 HIGH |
| The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. | |||||
| CVE-2023-50247 | 1 Dena | 1 H2o | 2023-12-19 | N/A | 7.5 HIGH |
| h2o is an HTTP server with support for HTTP/1.x, HTTP/2 and HTTP/3. The QUIC stack (quicly), as used by H2O up to commit 43f86e5 (in version 2.3.0-beta and prior), is susceptible to a state exhaustion attack. When H2O is serving HTTP/3, a remote attacker can exploit this vulnerability to progressively increase the memory retained by the QUIC stack. This can eventually cause H2O to abort due to memory exhaustion. The vulnerability has been resolved in commit d67e81d03be12a9d53dc8271af6530f40164cd35. HTTP/1 and HTTP/2 are not affected by this vulnerability as they do not use QUIC. Administrators looking to mitigate this issue without upgrading can disable HTTP/3 support. | |||||
| CVE-2017-10868 | 1 Dena | 1 H2o | 2021-08-12 | 5.0 MEDIUM | 7.5 HIGH |
| H2O version 2.2.2 and earlier allows remote attackers to cause a denial of service in the server via specially crafted HTTP/1 header. | |||||
| CVE-2017-10908 | 1 Dena | 1 H2o | 2021-04-19 | 5.0 MEDIUM | 7.5 HIGH |

| CVE-2017-10869 | 1 Dena | 1 H2o | 2021-04-19 | 5.0 MEDIUM | 7.5 HIGH |
| Buffer overflow in H2O version 2.2.2 and earlier allows remote attackers to cause a denial-of-service in the server via unspecified vectors. | |||||
| CVE-2016-4817 | 1 Dena | 1 H2o | 2021-04-19 | 5.0 MEDIUM | 7.5 HIGH |
| lib/http2/connection.c in H2O before 1.7.3 and 2.x before 2.0.0-beta5 mishandles HTTP/2 disconnection, which allows remote attackers to cause a denial of service (use-after-free and application crash) or possibly execute arbitrary code via a crafted packet. | |||||
| CVE-2016-4864 | 1 Dena | 1 H2o | 2019-02-26 | 5.0 MEDIUM | 7.5 HIGH |
| H2O versions 2.0.3 and earlier and 2.1.0-beta2 and earlier allows remote attackers to cause a denial-of-service (DoS) via format string specifiers in a template file via fastcgi, mruby, proxy, redirect or reproxy. | |||||
