{"id":"GHSA-8m9g-647g-5pxw","summary":"Infinite loop in Yubico yubihsm-connector","details":"An issue was discovered in the /api/connector endpoint handler in Yubico yubihsm-connector before 3.0.1 (in YubiHSM SDK before 2021.04). The handler did not validate the length of the request, which can lead to a state where yubihsm-connector becomes stuck in a loop waiting for the YubiHSM to send it data, preventing any further operations until the yubihsm-connector is restarted. An attacker can send 0, 1, or 2 bytes to trigger this.","aliases":["CVE-2021-28484"],"modified":"2023-11-08T04:05:30.407376Z","published":"2022-02-15T01:57:18Z","database_specific":{"cwe_ids":["CWE-835"],"github_reviewed_at":"2021-05-07T16:04:45Z","github_reviewed":true,"nvd_published_at":"2021-04-14T18:15:00Z","severity":"HIGH"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-28484"},{"type":"WEB","url":"https://github.com/Yubico/yubihsm-connector/commit/82bdf202c53460bac9106cc9b4b34a0a16cae0ed"},{"type":"WEB","url":"https://github.com/Yubico/yubihsm-connector/releases"},{"type":"WEB","url":"https://www.yubico.com/support/security-advisories/ysa-2021-02"}],"affected":[{"package":{"name":"github.com/Yubico/yubihsm-connector","ecosystem":"Go","purl":"pkg:golang/github.com/Yubico/yubihsm-connector"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.0.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/02/GHSA-8m9g-647g-5pxw/GHSA-8m9g-647g-5pxw.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:R"}]}
