{"id":"UBUNTU-CVE-2024-27983","details":"An attacker can make the Node.js HTTP/2 server completely unavailable by sending a small amount of HTTP/2 frames packets with a few HTTP/2 frames inside. It is possible to leave some data in nghttp2 memory after reset when headers with HTTP/2 CONTINUATION frame are sent to the server and then a TCP connection is abruptly closed by the client triggering the Http2Session destructor while header frames are still being processed (and stored in memory) causing a race condition.","modified":"2026-04-22T17:48:38.136379Z","published":"2024-04-09T01:15:00Z","upstream":["CVE-2024-27983"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-27983"},{"type":"REPORT","url":"https://nodejs.org/en/blog/vulnerability/april-2024-security-releases/"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-27983"},{"type":"REPORT","url":"https://github.com/nodejs/node/commit/0fb816dbccde955cd24acc1b16497a91fab507c8"}],"affected":[{"package":{"name":"nodejs","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/nodejs@10.19.0~dfsg-3ubuntu1.6+esm2?arch=source&distro=esm-apps/focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["10.15.2~dfsg-2ubuntu1","10.17.0~dfsg-2ubuntu4","10.17.0~dfsg-2ubuntu6","10.19.0~dfsg-3ubuntu1","10.19.0~dfsg-3ubuntu1.1","10.19.0~dfsg-3ubuntu1.2","10.19.0~dfsg-3ubuntu1.3","10.19.0~dfsg-3ubuntu1.5","10.19.0~dfsg-3ubuntu1.6","10.19.0~dfsg-3ubuntu1.6+esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"10.19.0~dfsg-3ubuntu1.6+esm2","binary_name":"libnode64"},{"binary_name":"nodejs","binary_version":"10.19.0~dfsg-3ubuntu1.6+esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-27983.json"}},{"package":{"name":"nodejs","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/nodejs@12.22.9~dfsg-1ubuntu3.6+esm2?arch=source&distro=esm-apps/jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["12.22.5~dfsg-5ubuntu1","12.22.7~dfsg-2ubuntu1","12.22.7~dfsg-2ubuntu3","12.22.9~dfsg-1ubuntu2","12.22.9~dfsg-1ubuntu3","12.22.9~dfsg-1ubuntu3.1","12.22.9~dfsg-1ubuntu3.2","12.22.9~dfsg-1ubuntu3.3","12.22.9~dfsg-1ubuntu3.4","12.22.9~dfsg-1ubuntu3.5","12.22.9~dfsg-1ubuntu3.6","12.22.9~dfsg-1ubuntu3.6+esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"libnode72","binary_version":"12.22.9~dfsg-1ubuntu3.6+esm2"},{"binary_name":"nodejs","binary_version":"12.22.9~dfsg-1ubuntu3.6+esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-27983.json"}},{"package":{"name":"nodejs","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/nodejs@18.19.1+dfsg-6ubuntu5?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["18.13.0+dfsg1-1ubuntu2","18.19.1+dfsg-2ubuntu4","18.19.1+dfsg-6ubuntu1","18.19.1+dfsg-6ubuntu2","18.19.1+dfsg-6ubuntu5"],"ecosystem_specific":{"binaries":[{"binary_name":"libnode109","binary_version":"18.19.1+dfsg-6ubuntu5"},{"binary_name":"nodejs","binary_version":"18.19.1+dfsg-6ubuntu5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-27983.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H"},{"type":"Ubuntu","score":"medium"}]}
