    Synopsis
    ========
    
    A buffer overflow in TigerVNC could result in execution of arbitrary
    code or Denial of Service.
    
    Background
    ==========
    
    TigerVNC is a high-performance VNC server/client.
    
    Affected packages
    =================
    
        -------------------------------------------------------------------
         Package              /     Vulnerable     /            Unaffected
        -------------------------------------------------------------------
      1  net-misc/tigervnc            < 1.3.1 >= 1.3.1
    
    Description
    ===========
    
    Two boundary errors in TigerVNC could lead to a heap-based buffer
    overflow.
    
    Impact
    ======
    
    A remote attacker could entice a user to connect to a malicious VNC
    server using TigerVNC, possibly resulting in execution of arbitrary
    code with the privileges of the process or a Denial of Service
    condition.
    
    Workaround
    ==========
    
    There is no known workaround at this time.
    
    Resolution
    ==========
    
    All TigerVNC users should upgrade to the latest version:
    
      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-misc/tigervnc-1.3.1"
