Description
It was discovered freeradius up to and including version 3.0.19 does not correctly configure logrotate, allowing a local attacker who already has control of the radiusd user to escalate his privileges to root, by tricking logrotate into writing a radiusd-writable file to a directory normally inaccessible by the radiusd user. NOTE: the upstream software maintainer has stated "there is simply no way for anyone to gain privileges through this alleged issue."
Affected configurations
• freeradius freeradius (<= 3.0.19)
• fedoraproject fedora 29
• fedoraproject fedora 30
• redhat enterprise linux 8.0
