{"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":"### Impact\n\nArbitrary shell execution is possible when using RPM::File#files and RPM::File#extract if the RPM contains a malicious \"payload compressor\" field.\n\nThis vulnerability impacts the `extract` and `files` methods of the `RPM::File` class in the affected versions of this library.\n\n### Patches\n\nVersion 0.0.12 is available with a fix for these issues.\n\n### Workarounds\n\nWhen using an affected version of this library (arr-pm), ensure any RPMs being processed contain valid/known payload compressor values. Such values include: gzip, bzip2, xz, zstd, and lzma.\n\nYou can check the payload compressor field in an rpm by using the rpm command line tool. For example:\n\n```\n% rpm -qp example-1.0-1.x86_64.rpm --qf \"%{PAYLOADCOMPRESSOR}\\n\"\ngzip\n```\n\n### Impact on known dependent projects\n\nThis library is used by [fpm](https://github.com/jordansissel/fpm). The vulnerability may impact fpm only when using the flag `-s rpm` or `--input-type rpm` to convert a malicious rpm to another format. It does not impact creating rpms.\n\n### References\n\n* https://github.com/jordansissel/ruby-arr-pm/pull/14\n* https://github.com/jordansissel/ruby-arr-pm/pull/15\n\n### Credit\n\nThanks to @joernchen for reporting this problem and contributing to the resolution :)\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n* Open an issue in [the arr-pm issue tracker](https://github.com/jordansissel/ruby-arr-pm/)\n\n","published":"2022-09-21T23:10:08Z","modified":"2026-10-28T02:31:13.130418292Z","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"},{"type":"PACKAGE","url":"https://github.com/jordansissel/ruby-arr-pm"},{"type":"WEB","url":"https://github.com/rubysec/ruby-advisory-db/blob/master/gems/arr-pm/CVE-2022-39224.yml"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:31:13.130418292Z"}}
