Echo: glib2.0: security update to 2.84.4-3~deb13u3+e3

high Tenable Self-Hosted Container Security Plugin ID 457307

Description

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

 - A flaw was found in GLib. A buffer over-read can occur in the g_regex_replace function when used with the
 `G_REGEX_RAW` compile flag and case-change replacement escapes because the string_append function
 processes matched substrings using UTF-8 functions that assume valid UTF-8 input, even when the string is
 treated as raw bytes. This vulnerability can cause a minor information disclosure of 1-5 bytes and a
 denial of service when the buffer over-read crosses a page boundary. (CVE-2026-58012)

Solution

Update the glib2.0 library and its related packages to version 2.84.4-3~deb13u3+e3 or later.
