Upgrade arr-pm to 0.0.12Run the following command in your project directory to verify that all resolved dependencies use the patched release:
inspect dependencies for arr-pmHow to Check if You Are Affected
To determine whether your application is affected by CVE-2022-39224, inspect your project dependencies for Arr pm:
inspect dependencies for arr-pmAnalyze the terminal output to locate any version of Arr pm in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.0.12), your application is affected.
Note: Verify declared build manifests and deployed runtime container environments.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Arr pm, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"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",
