The routine to check the log and report file permissions was not working as intended and could be bypassed locally. Because of the race, an unprivileged attacker can set up a log and report file, and control that up to the point where the specific routine is doing its check. After that, the file can be removed, recreated, and used for additional attacks.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:L","score":4.2},"cwes":["CWE-367"],"references":["https://cisofy.com/security/cve/cve-2020-13882/","https://cwe.mitre.org/data/definitions/367.html","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JDCHEKNR3HPJRNHE5PYKFH5GNBADTPA7/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UBFHIX6RTHCK37FXMAAXP4KGAMLUFDUD/","https://cisofy.com/security/cve/cve-2020-13882/"],"products":["cisofy:lynis","fedoraproject:fedora"],"source":"nvd","synced_at":"2026-10-19T21:05:42.039641217+00:00"},"epss":{"cve":"CVE-2020-13882","score":0.00256,"percentile":0.17267,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
