GHSA-88CV-MJ24-8W3Q
Vulnerability from github – Published: 2022-09-21 17:00 – Updated: 2022-09-21 17:00Impact
Arbitrary shell execution is possible when using RPM::File#files and RPM::File#extract if the RPM contains a malicious "payload compressor" field.
This vulnerability impacts the extract and files methods of the RPM::File class in the affected versions of this library.
Patches
Version 0.0.12 is available with a fix for these issues.
Workarounds
When 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.
You can check the payload compressor field in an rpm by using the rpm command line tool. For example:
% rpm -qp example-1.0-1.x86_64.rpm --qf "%{PAYLOADCOMPRESSOR}\n"
gzip
Impact on known dependent projects
This library is used by 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.
