{"id":"GHSA-fhr3-xh3q-69w6","summary":"uutils coreutils has an Incorrect Provision of Specified Functionality Issue","details":"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.","aliases":["CVE-2026-35379"],"modified":"2026-05-05T16:56:32.251660Z","published":"2026-04-22T18:31:46Z","database_specific":{"github_reviewed_at":"2026-04-30T18:04:14Z","nvd_published_at":"2026-04-22T17:16:42Z","cwe_ids":["CWE-684"],"severity":"LOW","github_reviewed":true},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35379"},{"type":"WEB","url":"https://github.com/uutils/coreutils/pull/11405"},{"type":"WEB","url":"https://github.com/uutils/coreutils/commit/358063f3367cb23a1e5db314cfdbfeb607749b3d"},{"type":"PACKAGE","url":"https://github.com/uutils/coreutils"},{"type":"WEB","url":"https://github.com/uutils/coreutils/releases/tag/0.8.0"}],"affected":[{"package":{"name":"coreutils","ecosystem":"crates.io","purl":"pkg:cargo/coreutils"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.8.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-fhr3-xh3q-69w6/GHSA-fhr3-xh3q-69w6.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"}]}
