Prior to version 2.1.4, a buffer that was used for inbound network traffic had no upper limit. Pion DTLS would buffer all network traffic from the remote user until the handshake completes or timed out. An attacker could exploit this to cause excessive memory usage. Version 2.1.4 contains a patch for this issue. There are currently no known workarounds available.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3},"cwes":["CWE-120"],"references":["https://github.com/pion/dtls/commit/a6397ff7282bc56dc37a68ea9211702edb4de1de","https://github.com/pion/dtls/releases/tag/v2.1.4","https://github.com/pion/dtls/security/advisories/GHSA-cx94-mrg9-rq4j","https://github.com/pion/dtls/commit/a6397ff7282bc56dc37a68ea9211702edb4de1de","https://github.com/pion/dtls/releases/tag/v2.1.4"],"products":["pion:dtls"],"source":"nvd","synced_at":"2026-10-19T21:31:59.322382750+00:00"},"epss":{"cve":"CVE-2022-29189","score":0.02149,"percentile":0.82127,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-cx94-mrg9-rq4j","url":"https://osv.dev/vulnerability/GHSA-cx94-mrg9-rq4j","summary":"Pion/DTLS contains buffer for inbound DTLS fragments with no limit","modified":"2023-11-08T04:09:09.299323Z","packages":[{"ecosystem":"Go","name":"github.com/pion/dtls","purl":"pkg:golang/github.com/pion/dtls","ranges":["<2.1.4"],"fixed":["2.1.4"]},{"ecosystem":"Go","name":"github.com/pion/dtls/v2","purl":"pkg:golang/github.com/pion/dtls/v2","ranges":["<2.1.4"],"fixed":["2.1.4"]}]},{"id":"GO-2022-0461","url":"https://osv.dev/vulnerability/GO-2022-0461","summary":"Unbounded memory consumption in github.com/pion/dtls/v2","modified":"2024-05-20T16:03:47Z","packages":[{"ecosystem":"Go","name":"github.com/pion/dtls/v2","purl":"pkg:golang/github.com/pion/dtls/v2","ranges":["<2.1.4"],"fixed":["2.1.4"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
