Synopsis

The remote openSUSE host is missing one or more security updates.

Description

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21228-1 advisory.

This update for glibc fixes the following issues

- CVE-2026-5435: unchecked buffer writing in TSIG handling can lead to an out-of-bounds write (bsc#1263656).
- CVE-2026-6238: insufficient RDATA length validation can lead to application crashes or uninitialized memory disclosure (bsc#1263658).
