{"id":"CVE-2022-39224","aliases":["GHSA-88cv-mj24-8w3q"],"url":"https://o3.security/vulnerability/CVE-2022-39224","summary":"Arbitrary shell execution when extracting or listing files contained in a malicious rpm.","details":"Arr-pm is an RPM reader/writer library written in Ruby. Versions prior to 0.0.12 are subject to OS command injection resulting in shell execution if the RPM contains a malicious \"payload compressor\" field. This vulnerability impacts the `extract` and `files` methods of the `RPM::File` class of this library. Version 0.0.12 patches these issues. A workaround for this issue is to ensure any RPMs being processed contain valid/known payload compressor values such as gzip, bzip2, xz, zstd, and lzma. The payload compressor field in an rpm can be checked by using the rpm command line tool.","published":"2022-09-21T23:10:08Z","modified":"2026-08-12T03:51:35.703621355Z","cvss":{"score":7,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":{"score":0.01573,"percentile":0.74214,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"RubyGems","name":"arr-pm","fixedVersion":"0.0.12"}],"fix":{"url":"https://github.com/jordansissel/ruby-arr-pm/pull/14","label":"jordansissel/ruby-arr-pm#14"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/39xxx/CVE-2022-39224.json"},{"type":"ADVISORY","url":"https://github.com/jordansissel/ruby-arr-pm/security/advisories/GHSA-88cv-mj24-8w3q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-39224"},{"type":"FIX","url":"https://github.com/jordansissel/ruby-arr-pm/pull/14"},{"type":"FIX","url":"https://github.com/jordansissel/ruby-arr-pm/pull/15"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:35.703621355Z"}}
