SUSE SLED15 / SLES15 Security Update : cloud-init (SUSE-SU-2019:3097-1)

medium Nessus Plugin ID 131558

Synopsis

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

Description

This update for cloud-init to version 19.2 fixes the following issues :

Security issue fixed :

CVE-2019-0816: Fixed the unnecessary extra ssh keys that were added to authorized_keys (bsc#1129124).

Non-security issues fixed: Short circuit the conditional for identifying the sysconfig renderer (bsc#1154092, bsc#1142988).

If /etc/resolv.conf is a symlink, break it. This will avoid netconfig from clobbering the changes cloud-init applied (bsc#1151488).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or 'zypper patch'.

Alternatively you can run the command listed for your product :
