DESCRIPTION:
Multiple vulnerabilities have been reported in ImageMagick, which can
be exploited by malicious people to cause a DoS (Denial of Service).

1) An error in the "GetEXIFProperty()" function (magick/property.c)
when parsing JPEG EXIF tags with a components count of 0 can be
exploited to access uninitialised or invalid memory via a specially
crafted JPEG image.

The vulnerability is reported in version 6.7.6-2 and prior.

2) Insufficient validation in the "JPEGWarningHandler()" function
(coders/jpeg.c) when handling JPEG restart markers may exhaust
resources via a specially crafted JPEG image.

The vulnerability is reported in version 6.7.6-2 and prior.

3) An error in the "TIFFGetEXIFProperties()" function (coders/tiff.c)
when parsing TIFF EXIF IFD may cause invalid memory to be read via a
specially crafted TIFF image.

The vulnerability is reported in version 6.7.6-2 and prior.

4) An integer overflow error in the "GetEXIFProperty()" function
(magick/property.c) when parsing JPEG EXIF tags with an overly large
components count may result in invalid heap memory being read. A
similar error exists in the "SyncImageProfiles()" function
(magick/profile.c).

The vulnerability is reported in versions prior to 6.7.6-4.

SOLUTION:
Update to version 6.7.6-4 or apply patches.
