sudo vulnerability: patch your systems
Attention masternode and systemnode operators, anyone running a linux wallet
Details were published yesterday about a nasty little bug in sudo which could allow any user in the sudo group to achieve full root access.
Are you affected?
Probably, if you’re running any version of sudo earlier than 1.8.28
How can you tell?
sudo -u#-1 /bin/sh
sudo -u#4294967295 /bin/sh
If you don’t get an error message then you need to apply a patch.
What should you do?
Hopefully your distro provider has already released a patch. Run your usual system update tool and retry the test above. If you don’t get an error then you need to contact your distro provider and ask them to provide a patch.
