Workaround
To mitigate this issue, avoid using `rpmbuild -t*` with tarballs whose paths or filenames can be influenced by untrusted input. In automated build pipelines, ensure tarballs are staged into a trusted local directory and their names are normalized or validated to reject shell metacharacters before `rpmbuild` is invoked.

| Description | A flaw was found in rpm. An attacker can exploit a command injection vulnerability by influencing the path or filename of a tarball processed by `rpmbuild -t*` to include shell metacharacters. This is particularly relevant in automated build or continuous integration (CI) workflows that ingest externally supplied artifact names. Successful exploitation allows for arbitrary command execution with the privileges of the build user, which could lead to information disclosure or disruption of the build environment. | |
