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.
