"It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-3125 advisory.

    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. (CVE-2026-78367)

    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-2026-84233)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
