ImageMagick 6.x < 6.9.6-5 TIFFGetProperties() NULL Pointer Dereference DoS
High Nessus Plugin ID 95719
SynopsisAn application installed on the remote Windows host is affected by a denial of service vulnerability.
DescriptionThe version of ImageMagick installed on the remote Windows host is 6.x prior to 6.9.6-5. It is, therefore, affected by a denial of service vulnerability due to a NULL pointer dereference flaw in the TIFFGetProperties() function within file coders/tiff.c.
An unauthenticated, remote attacker can exploit this, via a specially crafted TIFF image, to crash a process linked against the library.
SolutionUpgrade to ImageMagick version 6.9.6-5 or later. Note that you may also need to manually uninstall the vulnerable version from the system.
