Overview

Technical description

dpkg 1.15.9, 1.16.x before 1.16.14, and 1.17.x before 1.17.9 expect the patch program to be compliant with a need for the "C-style encoded filenames" feature, but is supported in environments with noncompliant patch programs, which triggers an interaction error that allows remote attackers to conduct directory traversal attacks and modify files outside of the intended directories via a crafted source package. NOTE: this vulnerability exists because of reliance on unrealistic constraints on the behavior of an external program.

Remediation

Check the references section for vendor advisories and patches from debian. Update dpkg to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
