    libvpx vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.04 ESM
    
    Summary:
    
    Several security issues were fixed in libvpx.
    
    Software Description:
    - libvpx: VP8 and VP9 video codec
    
    Details:
    
    USN-4199-1 fixed several vulnerabilities in libvpx. This update provides
    the corresponding update for Ubuntu 14.04 ESM.
    
    Original advisory details:
    
     It was discovered that libvpx did not properly handle certain malformed
     WebM media files. If an application using libvpx opened a specially crafted
     WebM file, a remote attacker could cause a denial of service, or possibly
     execute arbitrary code.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.04 ESM:
      libvpx1                         1.3.0-2ubuntu0.1~esm1
    
    In general, a standard system update will make all the necessary changes.
