Synopsis :

The application installed on the remote Windows host is affected by
multiple vulnerabilities.

Description :

The version of ImageMagick installed on the remote Windows host is 6.x
prior to 6.9.4-0 or 7.x prior to 7.0.1-2. It is, therefore, affected
by the following vulnerabilities :

- A flaw exists in the imagick Extension that allows an
unauthenticated, remote attacker to bypass the
'disable_functions' setting, resulting in the execution
of arbitrary commands or code. (VulnDB 138108)

- A buffer overflow condition exists in the
DrawStrokePolygon() function within file magick/draw.c
due to improper validation of user-supplied input. An
unauthenticated, remote attacker can exploit this to
cause a denial of service condition or the execution of
arbitrary code. (VulnDB 138399)

- An out-of-bounds read error exists in the
PushShortPixel() function within file coders/psd.c when
handling a specially crafted PSD file. An
unauthenticated, remote attacker can exploit this to
disclose sensitive information or cause a denial of
service condition. (VulnDB 138441)

- A buffer overflow condition exists in the
WritePixelCachePixels() function within file cache.c due
to improper validation of user-supplied input. An
unauthenticated, remote attacker can exploit this, via a
specially crafted PICT file, to cause a denial of
service condition or the execution of arbitrary code.
(VulnDB 138442)
