Echo: rpm: security update to 4.20.1+dfsg-3+e2

high Tenable Self-Hosted Container Security Plugin ID 474848

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A vulnerability was found in RPM's rpmbuild tarball processing. When processing a crafted source archive,
 the getTarSpec() function in tools/rpmbuild.cc passes an attacker-controlled tar archive member name to
 rpmExpand() as part of a %{basename:...} macro expression. A specially crafted .spec member name can
 therefore inject RPM macros, including Lua expressions, resulting in arbitrary code execution with the
 privileges of the user running rpmbuild. This can be exploited when a victim or automated build system
 processes an attacker-controlled source tarball using rpmbuild tarball mode (such as -ts, -ta, or -tb).
 (CVE-2026-78367)

Solution

Update the rpm library and its related packages to version 4.20.1+dfsg-3+e2 or later.
