17
18 A vulnerability was discovered in Asterisk which may allow local
19 attackers to gain root privileges.
20
21 Background
22 ==========
23
24 A Modular Open Source PBX System.
25
26 Affected packages
27 =================
28

34 Description
35 ===========
36
37 It was discovered that Gentoo’s Asterisk ebuild does not properly set
38 permissions on its data directories. This only affects OpenRC systems,
39 as the flaw was exploitable via the init script.
40
41 Impact
42 ======
43
44 A local attacker could escalate privileges.
45
46 Workaround
47 ==========
48
49 Users should ensure the proper permissions are set as discussed in the
50 referenced bugs. Do not run /etc/init.d/asterisk checkperms.
51
52 Resolution
53 ==========
54
55 All Asterisk users should upgrade to the latest version:
56
57 # emerge --sync
58 # emerge --ask --oneshot --verbose ">=net-misc/asterisk-13.32.0-r1"
