Echo: glibc: security update to 2.41-12+deb13u3+e5

high Tenable Cloud Security Plugin ID 457585

Description

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

- Calling strfmon and strfmon_l in the GNU C Library version 2.38 to 2.44 can write past the end of the
caller-supplied output buffer when a conversion uses right-justified width padding. Exploitation requires
an application code path that calls strfmon or strfmon_l with right-justified width padding into a
destination buffer that is large enough for the padding to succeed but too small for the internal memmove
call. The field width or format may be attacker-influenced or a fixed susceptible pattern in the caller.
At the time of publication, no network-facing application impact is known. (CVE-2026-19499)

Solution

Update the glibc library and its related packages to version 2.41-12+deb13u3+e5 or later.
