FreeRADIUS: Root privilege escalation — GLSA 202101-27

Multiple vulnerabilities were discovered in Gentoo's systemd unit for FreeRADIUS which could lead to root privilege escalation.

Package	net-dialup/freeradius on all architectures
Affected versions	< 3.0.20-r1
Unaffected versions	>= 3.0.20-r1

FreeRADIUS is a modular, high performance free RADIUS suite.

It was discovered that Gentoo’s FreeRADIUS systemd unit set permissions on an unsafe directory on start.

A local attacker could escalate privileges.

There is no known workaround at this time.

All FreeRADIUS users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-dialup/freeradius-3.0.20-r1"
