graphicsmagick 1.4~hg15896-1 source package in Ubuntu

Changelog

graphicsmagick (1.4~hg15896-1) unstable; urgency=high

  * Mercurial snapshot, fixing the following security issues:
    - ReadMNGImage(): Quit processing and report error upon failure to insert
      MNG background layer preventing out of memory issues,
    - ReadMIFFImage(): Improve pixel buffer calculations to defend against
      overflow,
    - ReadTIFFImage(): Make sure that image is in DirectClass mode and ignore
      any claimed colormap when the image is read using various functions,
    - ReadWPGImage(): Assure that all colormap entries are initialized,
    - DecodeImage(): Avoid a one-byte over-read of pixels heap allocation,
    - ReadTIFFImage(): Assure that opacity channel is initialized in the
      RGBAStrippedMethod case,
    - ReadMNGImage(): Bound maximum loop iterations by subrange as a
      primitive means of limiting resource consumption preventing out of
      memory issues,
    - CVE-2019-7397: WritePDFImage(): Make sure to free 'xref' before
      returning preventing several memory leaks,
    - ReadTIFFImage(): For planar TIFF, make sure that pixels are initialized
      in case some planes are missing.
