{"id":"CVE-2017-9226","details":"An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A heap out-of-bounds write or read occurs in next_state_val() during regular expression compilation. Octal numbers larger than 0xff are not handled correctly in fetch_token() and fetch_token_in_cc(). A malformed regular expression containing an octal number in the form of '\\700' would produce an invalid code point value larger than 0xff in next_state_val(), resulting in an out-of-bounds write memory corruption.","modified":"2026-05-17T11:54:32.702050037Z","published":"2017-05-24T15:29:00.277Z","related":["SUSE-SU-2017:1585-1","SUSE-SU-2017:1662-1","SUSE-SU-2017:1717-1"],"database_specific":{},"references":[{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/101244"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:1296"},{"type":"REPORT","url":"https://github.com/kkos/oniguruma/issues/55"},{"type":"FIX","url":"https://github.com/kkos/oniguruma/commit/b4bf968ad52afe14e60a2dc8a95d3555c543353a"},{"type":"FIX","url":"https://github.com/kkos/oniguruma/commit/f015fbdd95f76438cd86366467bb2b39870dd7c6"}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
