{"id":"GHSA-rx8h-33gr-vhj9","summary":"Duplicate Advisory: uutils coreutils' comm utility incorrectly consumes data from non-regular file inputs before performing comparison operations","details":"### Duplicate Advisory\nThis advisory has been withdrawn because it is a duplicate of GHSA-3wfc-mgpm-9rq6. This link is maintained to preserve external references.\n\n### Original Description\nThe comm utility in uutils coreutils incorrectly consumes data from non-regular file inputs before performing comparison operations. The are_files_identical function opens and reads from both input paths to compare content without first verifying if the paths refer to regular files. If an input path is a FIFO or a pipe, this pre-read operation drains the stream, leading to silent data loss before the actual comparison logic is executed. Additionally, the utility may hang indefinitely if it attempts to pre-read from infinite streams like /dev/zero.","modified":"2026-09-10T03:51:03.223570111Z","published":"2026-04-22T18:31:45Z","withdrawn":"2026-07-06T20:17:50Z","database_specific":{"nvd_published_at":"2026-04-22T17:16:36Z","cwe_ids":["CWE-20"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-04-29T23:03:27Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35347"},{"type":"WEB","url":"https://github.com/uutils/coreutils/pull/9545"},{"type":"WEB","url":"https://github.com/uutils/coreutils/commit/75f45e87e52ed95840494963ab9a28651165d56e"},{"type":"PACKAGE","url":"https://github.com/uutils/coreutils"},{"type":"WEB","url":"https://github.com/uutils/coreutils/releases/tag/0.6.0"}],"affected":[{"package":{"name":"coreutils","ecosystem":"crates.io","purl":"pkg:cargo/coreutils"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.6.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-rx8h-33gr-vhj9/GHSA-rx8h-33gr-vhj9.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:L"}]}
