{"id":"CVE-2020-8265","details":"Node.js versions before 10.23.1, 12.20.1, 14.15.4, 15.5.1 are vulnerable to a use-after-free bug in its TLS implementation. When writing to a TLS enabled socket, node::StreamBase::Write calls node::TLSWrap::DoWrite with a freshly allocated WriteWrap object as first argument. If the DoWrite method does not return an error, this object is passed back to the caller as part of a StreamWriteResult structure. This may be exploited to corrupt memory leading to a Denial of Service or potentially other exploits.","aliases":["BIT-node-2020-8265","BIT-node-min-2020-8265"],"modified":"2026-04-02T06:46:31.172379Z","published":"2021-01-06T21:15:14.410Z","related":["ALSA-2021:0548","ALSA-2021:0549","ALSA-2021:0551","MGASA-2021-0069","SUSE-SU-2021:0060-1","SUSE-SU-2021:0061-1","SUSE-SU-2021:0062-1","SUSE-SU-2021:0068-1","SUSE-SU-2021:0082-1","SUSE-SU-2021:0107-1","openSUSE-SU-2021:0064-1","openSUSE-SU-2021:0065-1","openSUSE-SU-2021:0066-1","openSUSE-SU-2021:0082-1","openSUSE-SU-2024:11096-1"],"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/H472D5HPXN6RRXCNFML3BK5OYC52CXF2/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/K4I6MZNC7C7VIDQR267OL4TVCI3ZKAC4/"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202101-07"},{"type":"ADVISORY","url":"https://www.debian.org/security/2021/dsa-4826"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20210212-0003/"},{"type":"ADVISORY","url":"https://www.oracle.com/security-alerts/cpujan2021.html"},{"type":"FIX","url":"https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf"},{"type":"FIX","url":"https://hackerone.com/reports/988103"},{"type":"FIX","url":"https://nodejs.org/en/blog/vulnerability/january-2021-security-releases/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/graalvm/graalvm-ce-builds","events":[{"introduced":"0"},{"last_affected":"4b00c1f1d35186b8ac562522370ad3982124bd80"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"19.3.4"}]}},{"type":"GIT","repo":"https://github.com/nodejs/node","events":[{"introduced":"cf41627411886000429bde058a6594fb7f6d6d47"},{"fixed":"811be91dfe623c7569f5fd87b1eaf46074334c94"},{"introduced":"2f45ad8060e13d5ac912335096d21526f2f9602b"},{"fixed":"87ddc7f10c6463bbcdd9dfc79f1e510a584e616e"},{"introduced":"73aa21658dfa6a22c06451d080152b32b1f98dbe"},{"fixed":"04509d6847a2d164b223a77aed0c41fe9ca60e57"},{"introduced":"d683e3dda09b6b3cc6cad6fd2c106e3061a48f0d"},{"fixed":"39fee5d91bc07beab14a1049358ababdd77ce3b1"},{"introduced":"0"},{"last_affected":"cf41627411886000429bde058a6594fb7f6d6d47"},{"introduced":"0"},{"last_affected":"57679e1c97a90057d5ca9e1f0d1f3c6255d20200"}],"database_specific":{"versions":[{"introduced":"10.0.0"},{"fixed":"10.23.1"},{"introduced":"12.0.0"},{"fixed":"12.20.1"},{"introduced":"14.0.0"},{"fixed":"14.15.4"},{"introduced":"15.0.0"},{"fixed":"15.5.1"},{"introduced":"0"},{"last_affected":"10.0"},{"introduced":"0"},{"last_affected":"20.3.0"}]}}],"versions":["v0.0.1","v0.0.2","v0.0.3","v0.0.4","v0.0.5","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","v0.1.90","v0.1.91","v0.1.92","v0.1.93","v0.1.94","v0.1.95","v0.1.96","v0.1.97","v0.1.98","v0.1.99","v0.10.0","v0.10.1","v0.10.10","v0.10.11","v0.10.12","v0.10.13","v0.10.14","v0.10.15","v0.10.16","v0.10.17","v0.10.18","v0.10.19","v0.10.2","v0.10.20","v0.10.21","v0.10.22","v0.10.23","v0.10.24","v0.10.25","v0.10.26","v0.10.27","v0.10.28","v0.10.29","v0.10.3","v0.10.30","v0.10.31","v0.10.32","v0.10.33","v0.10.34","v0.10.35","v0.10.36","v0.10.37","v0.10.38","v0.10.39","v0.10.4","v0.10.40","v0.10.41","v0.10.41-rc.1","v0.10.42","v0.10.43","v0.10.44","v0.10.45","v0.10.46","v0.10.47","v0.10.48","v0.10.5","v0.10.6","v0.10.7","v0.10.8","v0.10.9","v0.11.0","v0.11.1","v0.11.10","v0.11.11","v0.11.12","v0.11.13","v0.11.14","v0.11.15","v0.11.16","v0.11.2","v0.11.3","v0.11.4","v0.11.5","v0.11.6","v0.11.7","v0.11.8","v0.11.9","v0.12.0","v0.12.1","v0.12.10","v0.12.11","v0.12.12","v0.12.13","v0.12.14","v0.12.15","v0.12.16","v0.12.17","v0.12.18","v0.12.2","v0.12.3","v0.12.4","v0.12.5","v0.12.6","v0.12.7","v0.12.8","v0.12.8-rc.1","v0.12.9","v0.2.0","v0.2.1","v0.2.2","v0.2.3","v0.2.4","v0.2.5","v0.2.6","v0.3.0","v0.3.1","v0.3.2","v0.3.3","v0.3.4","v0.3.5","v0.3.6","v0.3.7","v0.3.8","v0.4.0","v0.4.1","v0.4.10","v0.4.11","v0.4.12","v0.4.2","v0.4.3","v0.4.4","v0.4.5","v0.4.6","v0.4.7","v0.4.8","v0.4.9","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","v0.6.10","v0.6.11","v0.6.12","v0.6.13","v0.6.14","v0.6.15","v0.6.16","v0.6.17","v0.6.18","v0.6.19","v0.6.2","v0.6.20","v0.6.21","v0.6.3","v0.6.4","v0.6.5","v0.6.6","v0.6.7","v0.6.8","v0.6.9","v0.7.0","v0.7.1","v0.7.10","v0.7.10-fixed","v0.7.11","v0.7.12","v0.7.2","v0.7.3","v0.7.4","v0.7.5","v0.7.6","v0.7.7","v0.7.8","v0.7.9","v0.8.0","v0.8.1","v0.8.10","v0.8.11","v0.8.12","v0.8.13","v0.8.14","v0.8.15","v0.8.16","v0.8.17","v0.8.18","v0.8.19","v0.8.2","v0.8.20","v0.8.21","v0.8.22","v0.8.23","v0.8.24","v0.8.2
