Notes
Topic: An update for Red Hat Hardened Images RPMs is now available.
Details: This update includes the following RPMs: rust-rpm-sequoia: * rpm-sequoia-1.10.1.1-1.2.hum1 (aarch64, x86_64) * rpm-sequoia-devel-1.10.1.1-1.2.hum1 (aarch64, x86_64) * rust-rpm-sequoia-1.10.1.1-1.2.hum1.src (src) Security Fix(es): rust-rpm-sequoia: * CVE-2026-2625

CVE-2026-2625

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.

4.0 (Medium)
CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
CWE-347 - Improper Verification of Cryptographic Signature
Vendor Fix For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ https://access.redhat.com/errata/RHSA-2026:12682
Workaround Avoid processing untrusted or attacker-controlled RPM files with rpm -Kv or rpm --checksig. Use isolated environments or additional validation layers when handling untrusted RPM artifacts.
