Doc Text:
A flaw was found in rust-rpm-sequoia. An attacker can exploit this vulnerability by providing a specially crafted Red Hat Package Manager (RPM) file. During the RPM signature verification process, this crafted file can trigger an error in the OpenPGP signature parsing code, leading to an unconditional termination of the rpm process. This issue results in an application level denial of service, making the system unable to process RPM files for signature verification.

Description OSIDB Bzimport 2026-02-17 13:12:49 UTC 
A crafted RPM file can trigger a Rust panic in the OpenPGP signature parsing code (librpm_sequoia) during RPM signature verification. The panic crosses the Rust/C FFI boundary and causes an unconditional abort of the rpm process, resulting in a denial of service. The issue is reachable via standard RPM CLI operations such as rpm -Kv and rpm --checksig without installing the package.

An attacker only needs to supply a specially crafted RPM file to a victim system where the RPM file is processed for signature verification (e.g., rpm -Kv, rpm --checksig, CI pipelines, or automated package validation workflows). No privileges, user interaction, or package installation are required.
