An\nattacker with access to precise enough timing and memory access information\n(typically an untrusted operating system attacking a secure enclave) could\nfully recover the ECC private key.\n\nFix issue in Lucky 13 counter-measure that could make it ineffective when\nhardware accelerators were used (using one of the MBEDTLS_SHAxxx_ALT macros).\nThis would cause the original Lucky 13 attack to be possible in those\nconfigurations, allowing an active network attacker to recover plaintext after\nrepeated timing measurements under some conditions.","dates":{"published":"2020-07-10T15:40:08.000Z","modified":"2026-04-16T04:25:48.165Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"mageia","product":"mbedtls","name":"mbedtls","label":"mbedtls","ecosystem":"Mageia","cpePart":null,"purl":"pkg:rpm/mageia/mbedtls","purlType":"rpm","versions":[{"text":"< 2.16.7-1.mga7","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 2.16.7-1.mga7","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://advisories.mageia.org/MGASA-2020-0293.html","label":"advisories.mageia.org/MGASA-2020-0293.html","hostname":"advisories.mageia.org","tags":["Advisory"]},{"url":"https://bugs.mageia.org/show_bug.cgi?id=26924","label":"bugs.mageia.org/show_bug.cgi?id=26924","hostname":"bugs.mageia.org","tags":["REPORT"]},{"url":"https://tls.mbed.org/tech-updates/security-advisories/mbedtls-security-advisory-2020-07","label":"tls.mbed.org/tech-updates/security-advisories/mbedtls-security-advisory-2020-07","hostname":"tls.mbed.org","tags":["Advisory"]},{"url":"https://github.com/ARMmbed/mbedtls/releases/tag/mbedtls-2.16.7","label":"github.com/ARMmbed/mbedtls/releases/tag/mbedtls-2.16.7","hostname":"github.com","tags":["WEB"]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2020-07-10T15:40:08.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-04-16T04:25:48.165Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":0,"level":"minimal","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-20T15:43:33.006Z","stale":false,"partial":false}}
