Summary
Package updates are available for Amazon Linux 2023 that fix the following vulnerabilities: CVE-2026-84233: 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. CVE-2026-78367: A flaw was found in rpmbuild. When rpmbuild processes a crafted tarball in tarball mode, a specially designed tar member name can lead to macro injection. This vulnerability allows a remote attacker to execute arbitrary code on the system by convincing a user to build a malicious tarball.
