This is associated with misinterpretion of an empty RPATH/RUNPATH token as the \"./\" directory. NOTE: this configuration of RPATH/RUNPATH for a privileged program is apparently very uncommon; most likely, no such program is shipped with any common Linux distribution.","published":"2017-12-18T01:29:00.000Z","lastModified":"2026-06-17T01:10:14.000Z","status":"Modified","sourceIdentifier":"security@debian.org","cvss":{"version":"3.0","score":7.8,"severity":"HIGH","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"cwe":["CWE-426"],"affected":["gnu/glibc","redhat/enterprise linux desktop","redhat/enterprise linux server","redhat/enterprise linux workstation"],"epss":{"score":0.02895,"percentile":0.86847,"date":"2026-10-27","history":[{"date":"2026-09-21","score":0.04856,"percentile":0.91648},{"date":"2026-09-22","score":0.02895,"percentile":0.86322}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (2.90%).
