    Synopsis
    ========
    
    A vulnerability was discovered in arpwatch which may allow local
    attackers to gain root privileges.
    
    Background
    ==========
    
    The ethernet monitor program; for keeping track of ethernet/ip address
    pairings.
    
    Affected packages
    =================
    
        -------------------------------------------------------------------
         Package              /     Vulnerable     /            Unaffected
        -------------------------------------------------------------------
      1  net-analyzer/arpwatch      < 2.1.15-r11            >= 2.1.15-r11
    
    Description
    ===========
    
    It was discovered that Gentoo’s arpwatch ebuild made excessive
    permission operations on its data directories, possibly changing
    ownership of unintended files. This only affects OpenRC systems, as the
    flaw was exploitable via the init script.
    
    Impact
    ======
    
    A local attacker could escalate privileges.
    
    Workaround
    ==========
    
    There is no known workaround at this time.
    
    Resolution
    ==========
    
    All arpwatch users should upgrade to the latest version:
    
      # emerge --sync
      # emerge --ask --oneshot -v ">=net-analyzer/arpwatch-2.1.15-r11"
