"The remote host is affected by the vulnerability described in GLSA-201612-55
(libjpeg-turbo: User-assisted execution of arbitrary code)

    The accelerated Huffman decoder was previously invoked if there were 128
      bytes in the input buffer. However, it is possible to construct a JPEG
      image with Huffman blocks > 430 bytes in length. This release simply
      increases the minimum buffer size for the accelerated Huffman decoder to
      512 bytes, which should accommodate any possible input.
  
Impact :

    A remote attacker could coerce the victim to run a specially crafted
      image file resulting in the execution of arbitrary code.
  
Workaround :

    There is no known workaround at this time."
