CVE-2018-1000168 4 Debian, Nghttp2, Nodejs and 1 more 4 Debian Linux, Nghttp2, Node.js and 1 more 2025-06-09 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 2025-06-09 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.
CVE-2020-11993 8 Apache, Canonical, Debian and 5 more 16 Http Server, Ubuntu Linux, Debian Linux and 13 more 2025-05-01 7.5 High
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.
