CVE-2017-9409

In ImageMagick 7.0.5-5, the ReadMPCImage function in mpc.c allows attackers to cause a denial of service (memory leak) via a crafted file.

This update for ImageMagick fixes several issues.

These security issues were fixed:

• CVE-2017-1000476: A CPU exhaustion vulnerability was found in the function ReadDDSInfo in coders/dds.c, which allowed attackers to cause a denial of service (bsc#1074610).
• CVE-2017-9409: The ReadMPCImage function in mpc.c allowed attackers to cause a denial of service (memory leak) via a crafted file (bsc#1042948).
• CVE-2017-1000445: A NULL pointer dereference in the MagickCore component might have lead to denial of service (bsc#1074425).
• CVE-2017-17680: Prevent a memory leak in the function ReadXPMImage in coders/xpm.c, which allowed attackers to cause a denial of service via a crafted XPM image file (a different vulnerability than CVE-2017-17882) (bsc#1072902).

• CVE-2017-11449: coders/mpc did not enable seekable streams and thus could not validate blob sizes, which allowed remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via an image received from stdin (bsc#1049373).
• CVE-2017-12430: A memory exhaustion in the function ReadMPCImage in coders/mpc.c allowed attackers to cause DoS (bsc#1052252).
• CVE-2017-12642: Prevent a memory leak vulnerability in ReadMPCImage in coders\mpc.c via crafted file allowing for DoS (bsc#1052771).
• CVE-2017-14249: A mishandled EOF check in ReadMPCImage in coders/mpc.c that lead to a division by zero in GetPixelCacheTileSize in MagickCore/cache.c allowed remote attackers to cause a denial of service via a crafted file (bsc#1058082).
• Prevent memory leak via crafted file in pwp.c allowing for DoS (bsc#1051412)

It was discovered that ImageMagick incorrectly handled certain malformed image files. If a user or automated system using ImageMagick were tricked into opening a specially crafted 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.
