SUSE SLES12 Security Update : sudo (SUSE-SU-2019:2668-1)

high Nessus Plugin ID 129963

Language:

Synopsis

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

Description

This update for sudo provides the following fix :

Security issue fixed :

CVE-2019-14287: Fixed an issue where a user with sudo privileges that allowed them to run commands with an arbitrary uid, could run commands as root, despite being forbidden to do so in sudoers (bsc#1153674).

Other issues fixed: Cache resolved group names as calling getgrgid() is expensive and on systems connected to AD with many users, groups or sudo rules it causes sudo to take a long time to run (bsc#1068003).

Disable insults by default at build time. For new installations this was done via sudoers file, but when upgrading from previous versions it would accidentally be enabled (bsc#1053911).

Enable support for zlib compressed I/O logs (bsc#1058297).

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 :

SUSE Linux Enterprise Server for SAP 12-SP1:zypper in -t patch SUSE-SLE-SAP-12-SP1-2019-2668=1
