GLSA-201701-16

The remote host is affected by the vulnerability described in GLSA-201701-16 (libTIFF: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in libTIFF. Please review       the CVE identifier and bug reports referenced for details.
  Impact :

    A remote attacker could entice a user to process a specially crafted       image file, 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.

Version 4.0.2-6+deb7u7 introduced changes that resulted in libtiff being unable to write out tiff files when the compression scheme in use relies on codec-specific TIFF tags embedded in the image.

This problem manifested itself with errors like those: $ tiffcp -r 16
-c jpeg sample.tif out.tif _TIFFVGetField: out.tif: Invalid tag 'Predictor' (not supported by codec). _TIFFVGetField: out.tif: Invalid tag 'BadFaxLines' (not supported by codec). tiffcp:
tif_dirwrite.c:687: TIFFWriteDirectorySec: Assertion `0' failed.

For Debian 7 'Wheezy', these problems have been fixed in version 4.0.2-6+deb7u10.

We recommend that you upgrade your tiff packages.
