{"id":"GHSA-88cv-mj24-8w3q","summary":"arr-pm vulnerable to 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","aliases":["CVE-2022-39224"],"modified":"2023-11-08T04:10:15.515035Z","published":"2022-09-21T17:00:12Z","database_specific":{"github_reviewed_at":"2022-09-21T17:00:12Z","nvd_published_at":"2022-09-21T23:15:00Z","cwe_ids":["CWE-78"],"severity":"HIGH","github_reviewed":true},"references":[{"type":"WEB","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":"WEB","url":"https://github.com/jordansissel/ruby-arr-pm/pull/14"},{"type":"WEB","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"}],"affected":[{"package":{"name":"arr-pm","ecosystem":"RubyGems","purl":"pkg:gem/arr-pm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.0.12"}]}],"versions":["0.0.10","0.0.11","0.0.2","0.0.3","0.0.4","0.0.5","0.0.6","0.0.7","0.0.8","0.0.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/09/GHSA-88cv-mj24-8w3q/GHSA-88cv-mj24-8w3q.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
