medium Tenable Self-Hosted Container Security Plugin ID 472744

Description

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

 - A flaw was found in dash. The printf builtin reserves four bytes before converting a Unicode \u or \U
 escape, but the multi-byte token can need five or six bytes. A local user who can supply such an escape to
 dash printf or echo %b, including through dash -c and a positional argument, can write one or two bytes
 past that reservation. (CVE-2026-102474)

Solution

Update the dash library and its related packages to version 0.5.12-12 or later.
