{"id":"CVE-2026-35368","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-35368","summary":"uutils coreutils has an Untrusted Search Path","details":"A vulnerability exists in the chroot utility of uutils coreutils when using the --userspec option. The utility resolves the user specification via getpwnam() after entering the chroot but before dropping root privileges. On glibc-based systems, this can trigger the Name Service Switch (NSS) to load shared libraries (e.g., libnss_*.so.2) from the new root directory. If the NEWROOT is writable by an attacker, they can inject a malicious NSS module to execute arbitrary code as root, facilitating a full container escape or privilege escalation.","published":"2026-04-22T18:31:45Z","modified":"2026-09-10T03:51:02.431988164Z","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H"},"epss":{"score":0.00136,"percentile":0.03396,"asOf":"2026-09-13"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"coreutils","fixedVersion":null}],"fix":null,"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35368"},{"type":"WEB","url":"https://github.com/uutils/coreutils/issues/10327"},{"type":"PACKAGE","url":"https://github.com/uutils/coreutils"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T03:51:02.431988164Z"}}
