{"id":"CVE-2026-35379","state":"PUBLISHED","title":"uutils coreutils tr Local Logic Error and Data Integrity Issue in Character Class Handling","description":"A logic error in the tr utility of uutils coreutils causes the program to incorrectly define the [:graph:] and [:print:] character classes. The implementation mistakenly includes the ASCII space character (0x20) in the [:graph:] class and excludes it from the [:print:] class, effectively reversing the standard behavior established by POSIX and GNU coreutils. This vulnerability leads to unintended data modification or loss when the utility is used in automated scripts or data-cleaning pipelines that rely on standard character class semantics. For example, a command executed to delete all graphical characters while intending to preserve whitespace will incorrectly delete all ASCII spaces, potentially resulting in data corruption or logic failures in downstream processing.","publishedAt":"2026-04-22T16:09:17.114Z","updatedAt":"2026-04-22T16:59:11.751Z","severity":{"score":3.3,"label":"Low","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"canonical"},"assigner":"canonical","products":["Uutils coreutils"],"affected":[{"vendor":"Uutils","product":"coreutils","packageName":"coreutils","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"0.8.0","versionType":"semver"}],"platforms":["Linux","Unix","macOS"],"collectionURL":"https://github.com/uutils","repo":"https://github.com/uutils/coreutils"}],"references":["https://github.com/uutils/coreutils/pull/11405","https://github.com/uutils/coreutils/releases/tag/0.8.0"],"weaknesses":["CWE-684"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/35xxx/CVE-2026-35379.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-35379","state":"PUBLISHED","datePublished":"2026-04-22T16:09:17.114Z","dateUpdated":"2026-04-22T16:59:11.751Z","assignerShortName":"canonical","assignerOrgId":"cc1ad9ee-3454-478d-9317-d3e869d708bc","dateReserved":"2026-04-02T12:58:56.089Z"},"containers":{"cna":{"title":"uutils coreutils tr Local Logic Error and Data Integrity Issue in Character Class Handling","descriptions":[{"lang":"en","value":"A logic error in the tr utility of uutils coreutils causes the program to incorrectly define the [:graph:] and [:print:] character classes.
