SUSE SLES15 Security Update : glibc (SUSE-SU-2026:2333-1)

critical Nessus Plugin ID 321044

Synopsis

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

Description

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:2333-1 advisory.

This update for glibc fixes the following issues

- CVE-2026-4046: assertion failure when converting inputs may be used to remotely crash an application (bsc#1261206).
- CVE-2026-5450: stdio-common: scanf %mc pattern will cause heap overflow when width > 1024 (bsc#1262465).
- CVE-2026-5928: libio: ungetwc could be used to leak data on special conditions (bsc#1262464).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
