Gentoo Linux Security Advisory

Title: Asterisk: Root privilege escalation (GLSA 202006-20)
Severity: high
Exploitable: local
Date: 2020-06-15
Bug(s): #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: net-misc/asterisk
Vulnerable: < 13.32.0-r1
Unaffected: >= 13.32.0-r1
Architectures: 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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=net-misc/asterisk-13.32.0-r1"
