    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
        -------------------------------------------------------------------
      1  net-misc/asterisk          < 13.32.0-r1            >= 13.32.0-r1 
    
    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"
