high Nessus Plugin ID 137457

Synopsis

Description

The remote host is affected by the vulnerability described in GLSA-202006-20 (Asterisk: Root privilege escalation)

 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.

Solution

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