{"id":"CVE-2019-16214","details":"Libra Core before 2019-09-03 has an erroneous regular expression for inline comments, which makes it easier for attackers to interfere with code auditing by using a nonstandard line-break character for a comment. For example, a Move module author can enter the // sequence (which introduces a single-line comment), followed by very brief comment text, the \\r character, and code that has security-critical functionality. In many popular environments, this code is displayed on a separate line, and thus a reader may infer that the code is executed. However, the code is NOT executed, because language/compiler/ir_to_bytecode/src/parser.rs allows the comment to continue after the \\r character.","modified":"2026-03-14T09:33:29.324928Z","published":"2019-09-11T04:15:11.887Z","references":[{"type":"ADVISORY","url":"https://blog.openzeppelin.com/libra-vulnerability-release/"},{"type":"FIX","url":"https://github.com/libra/libra/commit/7efb0221989f17fdf7f8486730898ed947a1e19e"},{"type":"EVIDENCE","url":"https://blog.openzeppelin.com/libra-vulnerability-summary/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/diem/diem","events":[{"introduced":"0"},{"fixed":"7efb0221989f17fdf7f8486730898ed947a1e19e"}]},{"type":"GIT","repo":"https://github.com/diem/diem","events":[{"introduced":"0"},{"fixed":"7efb0221989f17fdf7f8486730898ed947a1e19e"}]}],"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"2019-09-03"}]},{"events":[{"introduced":"0"},{"fixed":"2019-09-03"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2019-16214.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:H/A:N"}]}
