{"id":"CVE-2021-22883","details":"Node.js before 10.24.0, 12.21.0, 14.16.0, and 15.10.0 is vulnerable to a denial of service attack when too many connection attempts with an 'unknownProtocol' are established. This leads to a leak of file descriptors. If a file descriptor limit is configured on the system, then the server is unable to accept new connections and prevent the process also from opening, e.g. a file. If no file descriptor limit is configured, then this lead to an excessive memory usage and cause the system to run out of memory.","aliases":["BIT-node-2021-22883","BIT-node-min-2021-22883"],"modified":"2026-04-16T04:38:19.624495912Z","published":"2021-03-03T18:15:14.893Z","related":["ALSA-2021:0734","ALSA-2021:0735","ALSA-2021:0744","SUSE-SU-2021:0648-1","SUSE-SU-2021:0649-1","SUSE-SU-2021:0650-1","SUSE-SU-2021:0651-1","SUSE-SU-2021:0673-1","SUSE-SU-2021:0674-1","openSUSE-SU-2021:0356-1","openSUSE-SU-2021:0357-1","openSUSE-SU-2021:0372-1","openSUSE-SU-2024:11096-1"],"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F45Y7TXSU33MTKB6AGL2Q5V5ZOCNPKOG/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HSYFUGKFUSZ27M5TEZ3FKILWTWFJTFAZ/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/E4FRS5ZVK4ZQ7XIJQNGIKUXG2DJFHLO7/"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20210416-0001/"},{"type":"REPORT","url":"https://hackerone.com/reports/1043360"},{"type":"FIX","url":"https://nodejs.org/en/blog/vulnerability/february-2021-security-releases/"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpuApr2021.html"},{"type":"FIX","url":"https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf"},{"type":"FIX","url":"https://www.oracle.com//security-alerts/cpujul2021.html"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpuoct2021.html"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/graalvm/graalvm-ce-builds","events":[{"introduced":"0"},{"last_affected":"251e15bf41dcc0c1b4e3debdb7d01f7082734ddd"},{"introduced":"0"},{"last_affected":"3c6e4c01b14bb666c14501160ba526442b051b5a"},{"introduced":"0"},{"last_affected":"2ada493c63db015cc41bca1021f0e567f51893c6"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"19.3.5"},{"introduced":"0"},{"last_affected":"20.3.1.2"},{"introduced":"0"},{"last_affected":"21.0.0.2"}]}},{"type":"GIT","repo":"https://github.com/nodejs/node","events":[{"introduced":"cf41627411886000429bde058a6594fb7f6d6d47"},{"fixed":"ce800870b4206bafea2942f0b404a7f8f86a8bea"},{"introduced":"2f45ad8060e13d5ac912335096d21526f2f9602b"},{"fixed":"ab8d3c5a1262b4e04c0191a180914555d7c860c3"},{"introduced":"73aa21658dfa6a22c06451d080152b32b1f98dbe"},{"fixed":"bd60e93357a118204ea238d94e7a9e4209d93062"},{"introduced":"d683e3dda09b6b3cc6cad6fd2c106e3061a48f0d"},{"fixed":"7a4f260c5df43caa2f522e739b7cc3e7595d7e09"},{"introduced":"0"},{"fixed":"57679e1c97a90057d5ca9e1f0d1f3c6255d20200"}],"database_specific":{"versions":[{"introduced":"10.0.0"},{"fixed":"10.24.0"},{"introduced":"12.0.0"},{"fixed":"12.21.0"},{"introduced":"14.0.0"},{"fixed":"14.16.0"},{"introduced":"15.0.0"},{"fixed":"15.10.0"},{"introduced":"0"},{"fixed":"20.3"}]}}],"versions":["v0.0.1","v0.0.2","v0.0.3","v0.0.4","v0.0.6","v0.1.0","v0.1.1","v0.1.10","v0.1.100","v0.1.101","v0.1.102","v0.1.103","v0.1.104","v0.1.11","v0.1.12","v0.1.13","v0.1.14","v0.1.15","v0.1.16","v0.1.17","v0.1.18","v0.1.19","v0.1.2","v0.1.20","v0.1.21","v0.1.22","v0.1.23","v0.1.24","v0.1.25","v0.1.26","v0.1.27","v0.1.28","v0.1.29","v0.1.3","v0.1.30","v0.1.31","v0.1.32","v0.1.33","v0.1.4","v0.1.5","v0.1.6","v0.1.7","v0.1.8","v0.1.9","v0.1.92","v0.1.93","v0.1.94","v0.1.95","v0.1.96","v0.1.97","v0.1.98","v0.1.99","v0.2.0","v0.3.0","v0.3.1","v0.3.2","v0.3.4","v0.3.5","v0.3.6","v0.3.7","v0.3.8","v0.4.0","v0.5.0","v0.5.1","v0.5.10","v0.5.2","v0.5.3","v0.5.4","v0.5.5","v0.5.5-rc1","v0.5.6","v0.5.7","v0.5.8","v0.5.9","v0.6.0","v0.6.1","v0.7.0","v0.7.2","v0.7.3","v1.0.1","v1.0.1-release","v1.0.2","v1.0.2-release","v1.0.3","v1.0.4","v1.1.0","v1.2.0","v1.3.0","v1.4.1","v1.4.2","v1.4.3","v1.5.0","v1.5.1","v1.6.0","v1.6.1","v1.6.2","v1.6.3","v1.6.4","v1.7.0","v1.7.1","v10.0.0","v10.1.0","v10.10.0","v10.11.0","v10.12.0","v10.13.0","v10.14.0","v10.14.1","v10.14.2","v10.15.0","v10.15.1","v10.15.2","v10.15.3","v10.16.0","v10.16.1","v10.16.2","v10.16.3","v10.17.0","v10.18.0","v10.18.1","v10.19.0","v10.2.0","v10.2.1","v10.20.0","v10.20.1","v10.21.0","v10.22.0","v10.22.1","v10.23.0","v10.23.1","v10.23.2","v10.23.3","v10.3.0","v10.4.0","v10.4.1","v10.5.0","v10.6.0","v10.7.0","v10.8.0","v10.9.0","v12.0.0","v12.1.0","v12.10.0","v12.11.0","v12.11.1","v12.12.0","v12.13.0","v12.13.1","v12.14.0","v12.14.1","v12.15.0","v12.16.0","v12.16.1","v12.16.2","v12.16.3","v12.17.0","v12.18.0","v12.18.1","v12.18.2","v12.18.3","v12.18.4","v12.19.0","v12.19.1","v12.2.0","v12.20.0","v12.20.1","v12.20.2","v12.3.0","v12.3.1","v12.4.0","v12.5.0","v12.6.0","v12.7.0","v12.8.0","v12.8.1","v12.9.0","v12.9.1","v14.0.0","v14.1.0","v14.10.0","v14.10.1","v14.11.0","v14.12.0","v14.13.0","v14.13.1","v14.14.0","v14.15.0","v14.15.1","v14.15.2","v14.15.3","v14.15.4","v14.15.5","v14.2.0","v14.3.0","v14.4.0","v14.5.0","v14.6.0","v14.7.0","v14.8.0","v14.9.0","v15.0.0","v15.0.1","v15.1.0","v15.2.0","v15.2.1","v15.3.0","v15.4.0","v15.5.0","v15.5.1","v15.6.0","v15.7.0","v15
