Echo: glibc: security update to 2.41-12+deb13u3+e7

medium Tenable Cloud Security Plugin ID 459373

Description

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

 - Passing an effectively empty string to the `,ccs=` syntax extension of the mode argument in the `fopen`
 function in the GNU C Library version 2.45 or earlier may result in a heap buffer overflow when the mode
 string input to the function is attacker controlled. This usage pattern is not seen in applications in
 common GNU/Linux distributions and applications that process user-supplied values for `ccs` should not
 pass them through without validation. (CVE-2026-18374)

Solution

Update the glibc library and its related packages to version 2.41-12+deb13u3+e7 or later.
