Fix CVE-2012-3437 ImageMagick: Magick_png_malloc() size argument

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

This update fixes a large number of potential security problems due to insufficient data validation when parsing different input formats.
Most of those potential security problems do not have a CVE number assigned.

While the security implications of all of these problems are not all fully known, it is highly recommended to update.

The update fixes the following identified vulnerabilities :

CVE-2012-3437

Incorrect validation of PNG buffer size, leading to DoS using specially crafted PNG files.

CVE-2014-8354

Out of bounds memory access in resize

CVE-2014-8355

Buffer overflow in PCX reader

CVE-2014-8562

Buffer overflow in DCM readers

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Tom Lane discovered that ImageMagick would not always properly allocate memory. If a user or automated system using ImageMagick were tricked into opening a specially crafted PNG image, an attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program.

ImageMagick received fixes for a overflow in *png_malloc functions.
(CVE-2012-3437)

Updated imagemagick packages fix security vulnerability :

The Magick_png_malloc function in coders/png.c in ImageMagick 6.7.8-6 and earlier does not use the proper variable type for the allocation size, which might allow remote attackers to cause a denial of service (crash) via a crafted PNG file that triggers incorrect memory allocation (CVE-2012-3437).

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - ImageMagick: Insufficient shell characters filtering (CVE-2016-3714)

  - ImageMagick: NULL pointer dereference in CheckEventLogging function in MagickCore/log.c (CVE-2018-16328)

  - The Magick_png_malloc function in coders/png.c in ImageMagick 6.7.8 and earlier does not use the proper     variable type for the allocation size, which might allow remote attackers to cause a denial of service     (crash) via a crafted PNG file that triggers incorrect memory allocation. (CVE-2012-3437)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

A vulnerability has been found and corrected in imagemagick :

The Magick_png_malloc function in coders/png.c in ImageMagick 6.7.8-6 does not use the proper variable type for the allocation size, which might allow remote attackers to cause a denial of service (crash) via a crafted PNG file that triggers incorrect memory allocation (CVE-2012-3437).

The updated packages have been patched to correct this issue.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - ImageMagick: NULL pointer dereference in  GetMagickProperty function in MagickCore/property.c     (CVE-2018-16329)

  - The Magick_png_malloc function in coders/png.c in ImageMagick 6.7.8 and earlier does not use the proper     variable type for the allocation size, which might allow remote attackers to cause a denial of service     (crash) via a crafted PNG file that triggers incorrect memory allocation. (CVE-2012-3437)

  - Stack-based buffer overflow in the WritePSDImage function in coders/psd.c in ImageMagick 6.5.4 and earlier     allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a     large number of layers in a PSD image, involving the L%02ld string, a different vulnerability than     CVE-2014-2030. (CVE-2014-1947)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.
