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)\n\nA flaw was found in rpmuncompress. This command injection vulnerability allows a local attacker to execute arbitrary commands. This occurs when rpmuncompress processes a specially crafted archive filename containing shell metacharacters, which are not properly escaped before being passed to shell command strings. Successful exploitation requires user interaction, where a user or automated workflow invokes rpmuncompress on the malicious file, leading to high impact on the confidentiality, integrity, and availability of data accessible to the invoking user.(CVE-2026-84838)", "category":"general", "title":"Description" }, { "text":"An update for rpm is now available for openEuler-24.03-LTS-SP4.\n\nopenEuler Security has rated this update as having a security impact of high.

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.", "category":"description", "title":"Vulnerability Description" } ], "product_status":{ "fixed":[ "openEuler-24.03-LTS-SP4:rpm-4.18.2-42.oe2403sp4.src", "openEuler-24.03-LTS-SP4:rpm-help-4.18.2-42.oe2403sp4.noarch", "openEuler-24.03-LTS-SP4:python3-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-build-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-debuginfo-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-debugsource-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-devel-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-libs-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-plugin-systemd-inhibit-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:python3-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-build-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-debuginfo-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-debugsource-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-devel-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-libs-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-plugin-systemd-inhibit-4.18.2-42.oe2403sp4.x86_64" ] }, "remediations":[ { "product_ids":[ "openEuler-24.03-LTS-SP4:rpm-4.18.2-42.oe2403sp4.src", "openEuler-24.03-LTS-SP4:rpm-help-4.18.2-42.oe2403sp4.noarch", "openEuler-24.03-LTS-SP4:python3-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-build-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-debuginfo-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-debugsource-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-devel-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-libs-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-plugin-systemd-inhibit-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:python3-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-build-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-debuginfo-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-debugsource-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-devel-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-libs-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-plugin-systemd-inhibit-4.18.2-42.oe2403sp4.x86_64" ], "details":"rpm security update", "category":"vendor_fix", "url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4512" } ], "scores":[ { "cvss_v3":{ "baseSeverity":"HIGH", "baseScore":7.8, "vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H", "version":"3.1" }, "products":[ "openEuler-24.03-LTS-SP4:rpm-4.18.2-42.oe2403sp4.src", "openEuler-24.03-LTS-SP4:rpm-help-4.18.2-42.oe2403sp4.noarch", "openEuler-24.03-LTS-SP4:python3-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-build-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-debuginfo-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-debugsource-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-devel-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-libs-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:rpm-plugin-systemd-inhibit-4.18.2-42.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:python3-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-build-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-debuginfo-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-debugsource-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-devel-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-libs-4.18.2-42.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:rpm-plugin-systemd-inhibit-4.18.2-42.oe2403sp4.x86_64" ] } ], "threats":[ { "details":"High", "category":"impact" } ], "title":"CVE-2026-84837" }, { "cve":"CVE-2026-84838", "notes":[ { "text":"A flaw was found in rpmuncompress.
