Echo: glibc: security update to 2.41-12+deb13u2+e5

medium Tenable Self-Hosted Container Security Plugin ID 459380

Description

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

 - The deprecated functions ns_printrrf, ns_printrr and fp_nquery in the GNU C Library version 2.0.1 to
 version 2.43 fail to validate the RDATA content against the RDATA length in a DNS response when processing
 A6, CERT, LOC, TKEY or TSIG records, which may allow an attacker to craft a DNS response, causing a target
 application to crash or read uninitialized memory. These functions are for application debugging only and
 hence not in the path of code executed by the DNS resolver. Further, they have been deprecated since
 version 2.34 and should not be used by any new applications. Applications should consider porting away
 from these interfaces since they may be removed in future versions. (CVE-2026-6238)

Solution

Update the glibc library and its related packages to version 2.41-12+deb13u2+e5 or later.
