{"id":"CVE-2021-28848","details":"Mintty before 3.4.5 allows remote servers to cause a denial of service (Windows GUI hang) by telling the Mintty window to change its title repeatedly at high speed, which results in many SetWindowTextA or SetWindowTextW calls. In other words, it does not implement a usleep or similar delay upon processing a title change.","modified":"2026-10-16T08:07:52.420442188Z","published":"2021-06-03T12:15:07.757Z","database_specific":{},"references":[{"type":"ADVISORY","url":"https://mintty.github.io/"},{"type":"FIX","url":"https://github.com/mintty/mintty/commit/bd52109993440b6996760aaccb66e68e782762b9"},{"type":"FIX","url":"https://github.com/mintty/mintty/compare/3.4.4...3.4.5"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mintty/mintty","events":[{"introduced":"0"},{"fixed":"3ad9946764faa5a9ed4fe3dee07e5841cd61493d"},{"fixed":"bd52109993440b6996760aaccb66e68e782762b9"}],"database_specific":{"extracted_events":[{"cpe":"cpe:2.3:a:mintty_project:mintty:*:*:*:*:*:*:*:*","range":[{"introduced":"0"},{"fixed":"3.4.5"}],"source":"CPE_RANGE"},{"range":[{"fixed":"bd52109993440b6996760aaccb66e68e782762b9"}],"source":"REFERENCES_COMMIT"}]}}],"versions":["3.4.4","3.4.3","3.4.2","3.4.1","3.4.0","3.3.0","3.2.0","3.1.8","3.1.7","3.1.6","3.1.5","3.1.4","3.1.0","3.0.6","3.0.5","3.0.4","3.0.3","3.0.2","3.0.1","3.0.0","2.9.9","2.9.8","2.9.7","2.9.6","2.9.5","2.9.4","2.9.3","2.9.2","2.9.1","2.9.0","2.8.5","2.8.4","2.8.3","2.8.2","2.8.1","2.8.0","2.7.9","2.7.8","2.7.7","2.7.6","2.7.5","2.7.4","2.7.3","2.7.2","2.7.1","2.7.0","2.6.2","2.6.1","2.6.0","2.5.1","2.5.0","2.4.3","2.4.2","2.4.1","2.4.0","2.3.7release","2.3.6","2.3.5","2.3.4","2.3.3","2.3.2","2.3.1","2.2.4","2.2.3","2.2.2","2.2.1","2.1.5","2.1.4","2.1.3","2.1.1","2.0.3","2.0.2","2.0.1"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2021-28848.json","vanir_signatures":[{"source":"https://github.com/mintty/mintty/commit/bd52109993440b6996760aaccb66e68e782762b9","target":{"file":"src/termout.c","function":"do_winop"},"deprecated":false,"digest":{"length":2255,"function_hash":"28169650809378464349498538494502767073"},"id":"CVE-2021-28848-19fd5b93","signature_type":"Function","signature_version":"v1"},{"source":"https://github.com/mintty/mintty/commit/bd52109993440b6996760aaccb66e68e782762b9","target":{"file":"src/termout.c"},"deprecated":false,"digest":{"line_hashes":["317428911661926661868252761962027447717","112468394346120965518991236116403409257","168987099712524418904182299280483948441","311328272091108505432879204472786237116","197200895768927549944824240411251098537","266539331141809853349953574222369638921","220351794621176987917549291880673623645","170564355797638682455443791316418191088"],"threshold":0.9},"id":"CVE-2021-28848-6c06ef0e","signature_type":"Line","signature_version":"v1"}],"vanir_signatures_modified":"2026-10-16T08:07:52Z"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
