Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES12 host has a package installed that is affected by a vulnerability as referenced in the SUSE- SU-2025:3868-1 advisory.

Security issues fixed:
- Race condition during socket creation by chronyc allows privilege escalation from user chrony to root (bsc#1246544).

Other issues fixed:
- Improve connection retry intervals when facing NTS-KE related issues (bsc#1213551).
* nts: use shorter NTS-KE retry interval when network is down.
* ntp: don't adjust poll interval when waiting for NTS-KE.
