More information:

Multiple vulnerabilities have been found in imagemagick, an image processing toolkit.

  • CVE-2019-12974

    NULL pointer dereference in ReadPANGOImage and ReadVIDImage (coders/pango.c and coders/vid.c). This vulnerability might be leveraged by remote attackers to cause denial of service via crafted image data.

  • CVE-2019-13135

    Multiple use of uninitialized values in ReadCUTImage, UnpackWPG2Raster and UnpackWPGRaster (coders/wpg.c and coders/cut.c). These vulnerabilities might be leveraged by remote attackers to cause denial of service or unauthorized disclosure or modification of information via crafted image data.

  • CVE-2019-13295, CVE-2019-13297

    Multiple heap buffer over-reads in AdaptiveThresholdImage (magick/threshold.c). These vulnerabilities might be leveraged by remote attackers to cause denial of service or unauthorized disclosure or modification of information via crafted image data.

  • CVE-2019-13304, CVE-2019-13305, CVE-2019-13306

    Multiple stack buffer overflows in WritePNMImage (coders/pnm.c), leading to stack buffer over write up to ten bytes. Remote attackers might leverage these flaws to potentially perform code execution or denial of service.

For Debian 8 Jessie, these problems have been fixed in version 8:6.8.9.9-5+deb8u17.

We recommend that you upgrade your imagemagick packages.
