Amazon Linux 2 (EOS) Security Advisory: ALAS2-2026-4076
Advisory Released Date: 2026-11-09
Advisory Updated Date: 2026-11-09
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. (CVE-2026-84837)
A flaw was found in rpm. An attacker can supply a crafted manifest file that, when processed by a user or automation using `rpm -q -p` or similar manifest-processing flows, leads to arbitrary code execution. This occurs because manifest entries are unexpectedly macro-expanded before being opened, allowing embedded shell commands to run with the privileges of the `rpm` process. Successful exploitation can lead to a full compromise of confidentiality, integrity, and availability for the affected account. (CVE-2026-95519)
