Echo: glibc: security update to 2.41-12+deb13u3+e8

medium Tenable Self-Hosted Container Security Plugin ID 458910

Description

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

 - Converting crafted EUC_JISX0213 input to UCS-4 or the internal wide character encoding, for example with
 iconv, in the GNU C Library version 2.3 to 2.44 may result in the converter making no progress, causing
 the calling application to hang. Some EUC_JISX0213 sequences decode to two code points. If the output
 buffer has room for only the first one, the converter stores the second in the conversion state and
 returns E2BIG, but it never clears that pending character after emitting it on the next call. The
 converter then keeps emitting the pending character without consuming further input, so an application
 that retries the conversion loops forever. The input must be attacker controlled and the application must
 convert it with an output buffer small enough to split the two code points. Only the EUC_JISX0213
 character set is affected, which is not commonly used. The related defect in SHIFT_JISX0213 converter is
 tracked separately as CVE-2026-77117. (CVE-2026-80489)

Solution

Update the glibc library and its related packages to version 2.41-12+deb13u3+e8 or later.
