{"id":"CVE-2020-14147","details":"An integer overflow in the getnum function in lua_struct.c in Redis before 6.0.3 allows context-dependent attackers with permission to run Lua code in a Redis session to cause a denial of service (memory corruption and application crash) or possibly bypass intended sandbox restrictions via a large number, which triggers a stack-based buffer overflow. NOTE: this issue exists because of a CVE-2015-8080 regression.","modified":"2026-04-10T06:41:10.667658Z","published":"2020-06-15T18:15:14.990Z","related":["MGASA-2020-0312","openSUSE-SU-2020:1035-1"],"references":[{"type":"ADVISORY","url":"https://www.debian.org/security/2020/dsa-4731"},{"type":"ADVISORY","url":"https://www.oracle.com/security-alerts/cpujan2021.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00058.html"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202008-17"},{"type":"FIX","url":"https://github.com/antirez/redis/commit/ef764dde1cca2f25d00686673d1bc89448819571"},{"type":"FIX","url":"https://github.com/antirez/redis/pull/6875"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/antirez/redis","events":[{"introduced":"0"},{"fixed":"ef764dde1cca2f25d00686673d1bc89448819571"}]},{"type":"GIT","repo":"https://github.com/redis/redis","events":[{"introduced":"0"},{"fixed":"ce878b6ed5df1a7b3e87a8af2d1262de4c5bb828"},{"introduced":"17dfd7cabbf7954f92b7a1243d4bb27fee5d4500"},{"fixed":"7803b1148dafe65e2c7927eac7ce9e9ef729efc1"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"5.0.9"},{"introduced":"6.0.0"},{"fixed":"6.0.3"}]}}],"versions":["1.3.6","2.2-alpha0","2.2-alpha1","2.2-alpha2","2.2-alpha3","2.2-alpha4","2.2-alpha5","2.2-alpha6","2.2.0-rc1","2.3-alpha0","5.0-rc1","5.0-rc2","5.0-rc3","5.0-rc4","5.0-rc5","5.0-rc6","5.0.0","5.0.1","5.0.2","5.0.3","5.0.4","5.0.5","5.0.6","5.0.7","5.0.8","6.0.0","6.0.1","6.0.2","v1.3.10","v1.3.11","v1.3.7","v1.3.8","v1.3.9","v2.0.0-rc1","v2.1.1-watch","vm-playpen"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2020-14147.json","vanir_signatures":[{"signature_type":"Function","deprecated":false,"target":{"file":"deps/lua/src/lua_struct.c","function":"controloptions"},"source":"https://github.com/antirez/redis/commit/ef764dde1cca2f25d00686673d1bc89448819571","digest":{"function_hash":"285556551804856358181809971858790846830","length":535},"id":"CVE-2020-14147-1c9f15ff","signature_version":"v1"},{"signature_type":"Line","deprecated":false,"target":{"file":"deps/lua/src/lua_struct.c"},"source":"https://github.com/antirez/redis/commit/ef764dde1cca2f25d00686673d1bc89448819571","digest":{"threshold":0.9,"line_hashes":["134335090510338628569141842895565787666","129767963907433821863868325737636018053","300080779537829833533704011346679055977","150366785480519783601597766313455146941","291778318289862582589671380180879160640","334836077840905045155583947536240977132","204789960506117649192793862499828062137","206010478460804687345513953054922291922","273452596673789713237435221305689614452","224353343358345155052571137818636792223","149016652711686681273500497938298290981","88480705846654040951299849469807546662","276361046096231743424703405800731534378","307287750647995264489892449716195012064","38246228680553567486599359596671787366","263027252925130599613215470536067358578","2874506608442905135345185747778786999","47699769131658910848691075822501354908","249210679146172818636927068194179760061"]},"id":"CVE-2020-14147-8ad6483a","signature_version":"v1"},{"signature_type":"Function","deprecated":false,"target":{"file":"deps/lua/src/lua_struct.c","function":"optsize"},"source":"https://github.com/antirez/redis/commit/ef764dde1cca2f25d00686673d1bc89448819571","digest":{"function_hash":"4084196643356696974733906552222450367","length":647},"id":"CVE-2020-14147-a8de9166","signature_version":"v1"},{"signature_type":"Function","deprecated":false,"target":{"file":"deps/lua/src/lua_struct.c","function":"getnum"},"source":"https://github.com/antirez/redis/commit/ef764dde1cca2f25d00686673d1bc89448819571","digest":{"function_hash":"135527645391249101043499856436152069482","length":238},"id":"CVE-2020-14147-c76f01ae","signature_version":"v1"}],"vanir_signatures_modified":"2026-04-10T06:41:10Z","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"3.4"}]},{"events":[{"introduced":"0"},{"last_affected":"4.1"}]},{"events":[{"introduced":"0"},{"last_affected":"4.2"}]},{"events":[{"introduced":"0"},{"last_affected":"4.3"}]},{"events":[{"introduced":"0"},{"last_affected":"12.0"}]},{"events":[{"introduced":"0"},{"last_affected":"10.0"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H"}]}
