{"id":"UBUNTU-CVE-2025-49140","details":"Pion Interceptor is a framework for building RTP/RTCP communication software. Versions v0.1.36 through v0.1.38 contain a bug in a RTP packet factory that can be exploited to trigger a panic with Pion based SFU via crafted RTP packets, This only affect users that use pion/interceptor. Users should upgrade to v0.1.39 or later, which validates that: `padLen \u003e 0 && padLen \u003c= payloadLength` and return error  on overflow, avoiding panic. If upgrading is not possible, apply the patch from the pull request manually or drop packets whose P-bit is set but whose padLen is zero or larger than the remaining payload.","modified":"2026-05-20T16:23:31.901951432Z","published":"2025-06-09T22:15:00Z","upstream":["CVE-2025-49140"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-49140"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-49140"},{"type":"REPORT","url":"https://github.com/pion/interceptor/security/advisories/GHSA-f26w-gh5m-qq77"},{"type":"REPORT","url":"https://github.com/pion/webrtc/issues/3148"},{"type":"REPORT","url":"https://github.com/pion/interceptor/pull/338"},{"type":"REPORT","url":"https://github.com/pion/interceptor/commit/fa5b35ea867389cec33a9c82fffbd459ca8958e5"}],"affected":[{"package":{"name":"golang-github-pion-interceptor","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/golang-github-pion-interceptor?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.1.12-1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-pion-interceptor-dev","binary_version":"0.1.12-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-49140.json"}},{"package":{"name":"golang-github-pion-interceptor","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/golang-github-pion-interceptor?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.1.12-1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-pion-interceptor-dev","binary_version":"0.1.12-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-49140.json"}},{"package":{"name":"golang-github-pion-interceptor","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/golang-github-pion-interceptor?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.1.12-1","0.1.42-1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-pion-interceptor-dev","binary_version":"0.1.42-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-49140.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
