{"id":"CURL-CVE-2016-8621","summary":"curl_getdate read out of bounds","details":"The `curl_getdate` converts a given date string into a numerical timestamp and\nit supports a range of different formats and possibilities to express a date\nand time. The underlying date parsing function is also used internally when\nparsing for example HTTP cookies (possibly received from remote servers) and\nit can be used when doing conditional HTTP requests.\n\nThe date parser function uses the libc `sscanf()` function at two places, with\nthe parsing strings `%02d:%02d` and `%02d:%02d:%02d`. The intent being that it\nwould parse either a string with HH:MM (two digits colon two digits) or\n`HH:MM:SS` (two digits colon two digits colon two digits). If instead the\npiece of time that was sent in had the final digit cut off, thus ending with a\nsingle-digit, the date parser code would advance its read pointer one byte too\nmuch and end up reading out of bounds.","aliases":["CVE-2016-8621"],"modified":"2026-04-25T20:30:37.528311Z","published":"2016-11-02T08:00:00Z","database_specific":{"last_affected":"7.50.3","severity":"Medium","CWE":{"desc":"Buffer Over-read","id":"CWE-126"},"www":"https://curl.se/docs/CVE-2016-8621.html","affects":"both","URL":"https://curl.se/docs/CVE-2016-8621.json","package":"curl"},"affected":[{"ranges":[{"type":"SEMVER","events":[{"introduced":"7.12.2"},{"fixed":"7.51.0"}]},{"type":"GIT","repo":"https://github.com/curl/curl.git","events":[{"introduced":"f6433211ae9afb30ec461e6633dafc6d8c77eaa9"},{"fixed":"96a80b5a262fb6dd2ddcea7987296f3b9a405618"}]}],"versions":["7.50.3","7.50.2","7.50.1","7.50.0","7.49.1","7.49.0","7.48.0","7.47.1","7.47.0","7.46.0","7.45.0","7.44.0","7.43.0","7.42.1","7.42.0","7.41.0","7.40.0","7.39.0","7.38.0","7.37.1","7.37.0","7.36.0","7.35.0","7.34.0","7.33.0","7.32.0","7.31.0","7.30.0","7.29.0","7.28.1","7.28.0","7.27.0","7.26.0","7.25.0","7.24.0","7.23.1","7.23.0","7.22.0","7.21.7","7.21.6","7.21.5","7.21.4","7.21.3","7.21.2","7.21.1","7.21.0","7.20.1","7.20.0","7.19.7","7.19.6","7.19.5","7.19.4","7.19.3","7.19.2","7.19.1","7.19.0","7.18.2","7.18.1","7.18.0","7.17.1","7.17.0","7.16.4","7.16.3","7.16.2","7.16.1","7.16.0","7.15.5","7.15.4","7.15.3","7.15.2","7.15.1","7.15.0","7.14.1","7.14.0","7.13.2","7.13.1","7.13.0","7.12.3","7.12.2"],"database_specific":{"vanir_signatures_modified":"2026-04-25T20:30:37Z","vanir_signatures":[{"target":{"file":"lib/parsedate.c"},"id":"CURL-CVE-2016-8621-16ef9308","signature_version":"v1","digest":{"threshold":0.9,"line_hashes":["308577960542575037336868169102471521462","13161730274141808989736688002385614941","44441430585724749763685529690364700466","323839820629539738068912297904044425666","36121451579133397473220353944741700271","36610642193482551647895047129290017031","13113538613352150690506112937236587324","181845228133792140107326450073547106629","249811738674333916540410957268716363404","288036674292455837486088679176124886884","22607342827772394773839602858200661227","203700620895711925919015838943376886808"]},"signature_type":"Line","deprecated":false,"source":"https://github.com/curl/curl.git/commit/96a80b5a262fb6dd2ddcea7987296f3b9a405618"},{"target":{"file":"lib/parsedate.c","function":"parsedate"},"id":"CURL-CVE-2016-8621-31fc78b9","signature_version":"v1","digest":{"length":3177,"function_hash":"60763901367296310916067366455512337471"},"signature_type":"Function","deprecated":false,"source":"https://github.com/curl/curl.git/commit/96a80b5a262fb6dd2ddcea7987296f3b9a405618"},{"target":{"file":"tests/libtest/lib517.c"},"id":"CURL-CVE-2016-8621-5f8cf6f0","signature_version":"v1","digest":{"threshold":0.9,"line_hashes":["4482088587697448749067670462751564421","172707527782089805535023746377141888104","95266190109046364501215603283468073662","90236223273100018790390633626959698097","67830574022030266779563003670359755773"]},"signature_type":"Line","deprecated":false,"source":"https://github.com/curl/curl.git/commit/96a80b5a262fb6dd2ddcea7987296f3b9a405618"}],"source":"https://curl.se/docs/CURL-CVE-2016-8621.json"}}],"schema_version":"1.7.5","credits":[{"name":"Luật Nguyễn","type":"FINDER"},{"name":"Daniel Stenberg","type":"REMEDIATION_DEVELOPER"}]}
