Echo: zbar: security update to 0.23.93-8+e1

medium Tenable Self-Hosted Container Security Plugin ID 474780

Description

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

 - ZBar commit 2ea2ca58 contains an undefined-behavior vulnerability in the Code 128 decode6() function. When
 processing specially crafted Code 128 input, decode_e() can return -1 for an invalid edge pattern, and
 decode6() subsequently left-shifts this negative signed value while constructing the edge signature. The
 operation invokes undefined behavior and can terminate trap-mode UBSan builds with SIGILL, resulting in
 denial of service. (CVE-2026-88371)

Solution

Update the zbar library and its related packages to version 0.23.93-8+e1 or later.
