{"id":"CVE-2017-9502","details":"In curl before 7.54.1 on Windows and DOS, libcurl's default protocol function, which is the logic that allows an application to set which protocol libcurl should attempt to use when given a URL without a scheme part, had a flaw that could lead to it overwriting a heap based memory buffer with seven bytes. If the default protocol is specified to be FILE or a file: URL lacks two slashes, the given \"URL\" starts with a drive letter, and libcurl is built for Windows or DOS, then libcurl would copy the path 7 bytes off, so that the end of the given path would write beyond the malloc buffer (7 bytes being the length in bytes of the ascii string \"file://\").","aliases":["CURL-CVE-2017-9502"],"modified":"2026-04-10T04:02:24.865678Z","published":"2017-06-14T13:29:00.747Z","related":["openSUSE-SU-2024:10582-1"],"references":[{"type":"WEB","url":"http://www.securitytracker.com/id/1038697"},{"type":"ADVISORY","url":"http://openwall.com/lists/oss-security/2017/06/14/1"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/99120"},{"type":"ADVISORY","url":"https://curl.haxx.se/docs/adv_20170614.html"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/curl/curl","events":[{"introduced":"0"},{"last_affected":"d957e2189fdc73cef0ff3d1fb58043d354754449"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"7.54.0"}]}}],"versions":["before_ftp_statemachine","before_urldata_rename","curl-6_5","curl-6_5_1","curl-6_5_2","curl-7_10","curl-7_10_1","curl-7_10_2","curl-7_10_3","curl-7_10_4","curl-7_10_5","curl-7_10_6","curl-7_10_7","curl-7_10_8","curl-7_11_0","curl-7_11_1","curl-7_11_2","curl-7_12_0","curl-7_12_1","curl-7_12_2","curl-7_12_3","curl-7_13_0","curl-7_13_1","curl-7_13_2","curl-7_14_0","curl-7_14_1","curl-7_15_0","curl-7_15_1","curl-7_15_2","curl-7_15_3","curl-7_15_4","curl-7_15_5","curl-7_15_6-prepipeline","curl-7_16_0","curl-7_16_1","curl-7_16_2","curl-7_16_3","curl-7_16_4","curl-7_17_0","curl-7_17_0-preldapfix","curl-7_17_1","curl-7_18_0","curl-7_18_1","curl-7_18_2","curl-7_19_0","curl-7_19_1","curl-7_19_2","curl-7_19_3","curl-7_19_4","curl-7_19_5","curl-7_19_6","curl-7_19_7","curl-7_1_1","curl-7_2","curl-7_20_0","curl-7_20_1","curl-7_21_0","curl-7_21_1","curl-7_21_2","curl-7_21_3","curl-7_21_4","curl-7_21_5","curl-7_21_6","curl-7_21_7","curl-7_22_0","curl-7_23_0","curl-7_23_1","curl-7_25_0","curl-7_26_0","curl-7_27_0","curl-7_28_0","curl-7_28_1","curl-7_29_0","curl-7_3","curl-7_30_0","curl-7_31_0","curl-7_32_0","curl-7_33_0","curl-7_34_0","curl-7_35_0","curl-7_36_0","curl-7_37_0","curl-7_37_1","curl-7_38_0","curl-7_39_0","curl-7_40_0","curl-7_41_0","curl-7_42_0","curl-7_43_0","curl-7_44_0","curl-7_45_0","curl-7_46_0","curl-7_47_0","curl-7_47_1","curl-7_48_0","curl-7_49_0","curl-7_49_1","curl-7_4_1","curl-7_5","curl-7_50_0","curl-7_50_1","curl-7_50_2","curl-7_50_3","curl-7_51_0","curl-7_52_0","curl-7_52_1","curl-7_53_0","curl-7_53_1","curl-7_54_0","curl-7_5_2","curl-7_6","curl-7_6-pre4","curl-7_6_1","curl-7_6_1-pre1","curl-7_6_1-pre2","curl-7_6_1-pre3","curl-7_7","curl-7_7-beta1","curl-7_7-beta2","curl-7_7-beta3","curl-7_7-beta5","curl-7_7_1","curl-7_7_2","curl-7_7_3","curl-7_7_alpha2","curl-7_8","curl-7_8-pre2","curl-7_8_1","curl-7_8_1-pre3","curl-7_9","curl-7_9_1","curl-7_9_2","curl-7_9_3","curl-7_9_3-pre1","curl-7_9_3-pre2","curl-7_9_3-pre3","curl-7_9_4","curl-7_9_5","curl-7_9_5-pre2","curl-7_9_5-pre4","curl-7_9_6","curl-7_9_7","curl-7_9_7-pre2","curl-7_9_8","curl_7_6-pre3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2017-9502.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"}]}
