NVD Description

Note: Versions mentioned in the description apply only to the upstream rpm-plugin-ima-debuginfo package and not the rpm-plugin-ima-debuginfo package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2023 relevant fixed versions and status.

A flaw was found in rpm. A local attacker could supply a specially crafted .gem filename containing RPM macro syntax. When a user or automated workflow invokes rpmuncompress -x on this file, the macro expansion occurs during command construction. This allows the attacker to execute arbitrary commands with the privileges of the invoking account, leading to a compromise of confidentiality, integrity, and availability.
