CVE-2023-35945 3 Envoyproxy, Nghttp2, Redhat 3 Envoy, Nghttp2, Service Mesh 2024-10-31 7.5 High
Envoy is a cloud-native high-performance edge/middle/service proxy. Envoy’s HTTP/2 codec may leak a header map and bookkeeping structures upon receiving `RST_STREAM` immediately followed by the `GOAWAY` frames from an upstream server. In nghttp2, cleanup of pending requests due to receipt of the `GOAWAY` frame skips de-allocation of the bookkeeping structure and pending compressed header. The error return [code path] is taken if connection is already marked for not sending more requests due to `GOAWAY` frame. The clean-up code is right after the return statement, causing memory leak. Denial of service through memory exhaustion. This vulnerability was patched in versions(s) 1.26.3, 1.25.8, 1.24.9, 1.23.11.
CVE-2024-28182 2 Nghttp2, Redhat 7 Nghttp2, Enterprise Linux, Jboss Core Services and 4 more 2024-09-27 5.3 Medium
nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C. The nghttp2 library prior to version 1.61.0 keeps reading the unbounded number of HTTP/2 CONTINUATION frames even after a stream is reset to keep HPACK context in sync. This causes excessive CPU usage to decode HPACK stream. nghttp2 v1.61.0 mitigates this vulnerability by limiting the number of CONTINUATION frames it accepts per stream. There is no workaround for this vulnerability.
CVE-2023-44487 32 Akka, Amazon, Apache and 29 more 364 Http Server, Opensearch Data Prepper, Apisix and 361 more 2024-08-19 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-2015-8659 2 Apple, Nghttp2 5 Iphone Os, Mac Os X, Tvos and 2 more 2024-08-06 N/A
The idle stream handling in nghttp2 before 1.6.0 allows attackers to have unspecified impact via unknown vectors, aka a heap-use-after-free bug.
CVE-2016-1544 2 Fedoraproject, Nghttp2 2 Fedora, Nghttp2 2024-08-05 3.3 Low
nghttp2 before 1.7.1 allows remote attackers to cause a denial of service (memory exhaustion).
CVE-2018-1000168 4 Debian, Nghttp2, Nodejs and 1 more 4 Debian Linux, Nghttp2, Node.js and 1 more 2024-08-05 7.5 High
nghttp2 version >= 1.10.0 and nghttp2 <= v1.31.0 contains an Improper Input Validation CWE-20 vulnerability in ALTSVC frame handling that can result in segmentation fault leading to denial of service. This attack appears to be exploitable via network client. This vulnerability appears to have been fixed in >= 1.31.1.
CVE-2020-11080 7 Debian, Fedoraproject, Nghttp2 and 4 more 16 Debian Linux, Fedora, Nghttp2 and 13 more 2024-08-04 3.7 Low
In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service. The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of 14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at 100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame and the number of settings entries are large (e.g., > 32), then drop the connection.
