Echo: dpkg: security update to 1.21.22-e1

high Tenable Self-Hosted Container Security Plugin ID 457227

Description

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

 - It was discovered that dpkg-deb does not properly sanitize directory permissions when extracting a control
 member into a temporary directory, which is documented as being a safe operation even on untrusted data.
 This may result in leaving temporary files behind on cleanup. Given automated and repeated execution of
 dpkg-deb commands on adversarial .deb packages or with well compressible files, placed inside a directory
 with permissions not allowing removal by a non-root user, this can end up in a DoS scenario due to causing
 disk quota exhaustion or disk full conditions. (CVE-2025-6297)

Solution

Update the dpkg library and its related packages to version 1.21.22-e1 or later.
