Prior to 4.3.0, Svc::TlmPacketizer TlmRecv_handler fixed-slot copy TlmRecv_handler copies val.getSize bytes into entry.channelSize storage without confirming that the runtime value fits. When a telemetry update for a configured channel carries a serialized value larger than that channel fixed slot, the copy overwrites adjacent channel fields and causes corrupted packetized telemetry to be emitted. This issue is fixed in version 4.3.0.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","cwes":["CWE-130","CWE-805"],"vendors":[],"products":[],"references":[{"url":"https://github.com/nasa/fprime/commit/048fe04062b91be7af138df7e09cdd15812dde96","tags":[]},{"url":"https://github.com/nasa/fprime/commit/7eacd551aaf6d9a21e347ac2c8d827ca15ee5755","tags":[]},{"url":"https://github.com/nasa/fprime/pull/4878","tags":[]},{"url":"https://github.com/nasa/fprime/releases/tag/v4.3.0a1","tags":[]},{"url":"https://github.com/nasa/fprime/security/advisories/GHSA-grrq-8rmr-xf83","tags":[]},{"url":"https://github.com/nasa/fprime/security/advisories/GHSA-grrq-8rmr-xf83","tags":[]}],"exploitRefs":[{"url":"https://github.com/nasa/fprime/commit/048fe04062b91be7af138df7e09cdd15812dde96","tags":[]},{"url":"https://github.com/nasa/fprime/commit/7eacd551aaf6d9a21e347ac2c8d827ca15ee5755","tags":[]},{"url":"https://github.com/nasa/fprime/pull/4878","tags":[]},{"url":"https://github.com/nasa/fprime/releases/tag/v4.3.0a1","tags":[]},{"url":"https://github.com/nasa/fprime/security/advisories/GHSA-grrq-8rmr-xf83","tags":[]},{"url":"https://github.com/nasa/fprime/security/advisories/GHSA-grrq-8rmr-xf83","tags":[]}],"hasPoc":true,"ai":null}
