Severity:	high
Title:	Asterisk: Root privilege escalation
Date:	06/15/2020
Bugs:	#602722
ID:	202006-20

Synopsis

A vulnerability was discovered in Asterisk which may allow local attackers to gain root privileges.

Background

A Modular Open Source PBX System.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-misc/asterisk	< 13.32.0-r1	>= 13.32.0-r1	All supported architectures

Description

It was discovered that Gentoo’s Asterisk ebuild does not properly set permissions on its data directories. This only affects OpenRC systems, as the flaw was exploitable via the init script.

Impact

A local attacker could escalate privileges.

Workaround

Users should ensure the proper permissions are set as discussed in the referenced bugs. Do not run /etc/init.d/asterisk checkperms.

Resolution

All Asterisk users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-misc/asterisk-13.32.0-r1"
