Echo: patch: security update to 2.8-2+e6

medium Tenable Cloud Security Plugin ID 477488

Description

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

 - A flaw was found in GNU patch. An attacker can achieve arbitrary file creation outside the intended
 working directory by enticing a user or automated workflow to apply a specially crafted patch file. Due to
 missing validation during automatic patch reversal, absolute file paths in patch headers are accepted
 rather than rejected. Consequently, the utility can create files in arbitrary locations with the
 permissions of the executing user. (CVE-2026-115207)

Solution

Update the patch library and its related packages to version 2.8-2+e6 or later.
