In ImageMagick before 7.0.8-8, a NULL pointer dereference exists in the CheckEventLogging function in MagickCore/log.c.

These are all security issues fixed in the ImageMagick-7.1.0.9-1.1 package on the GA media of openSUSE Tumbleweed.

This update for ImageMagick fixes the following security issues:

• CVE-2018-16413: Prevent heap-based buffer over-read in the PushShortPixel function leading to DoS (bsc#1106989)
• CVE-2018-16329: Prevent NULL pointer dereference in the GetMagickProperty function leading to DoS (bsc#1106858).
• CVE-2018-16328: Prevent NULL pointer dereference exists in the CheckEventLogging function leading to DoS (bsc#1106857).
• CVE-2018-16323: ReadXBMImage left data uninitialized when processing an XBM file that has a negative pixel value. If the affected code was used as a library loaded into a process that includes sensitive information, that information sometimes can be leaked via the image data (bsc#1106855)
• CVE-2018-16642: The function InsertRow allowed remote attackers to cause a denial of service via a crafted image file due to an out-of-bounds write (bsc#1107616)
• CVE-2018-16640: Prevent memory leak in the function ReadOneJNGImage (bsc#1107619)
• CVE-2018-16641: Prevent memory leak in the TIFFWritePhotoshopLayers function (bsc#1107618).
• CVE-2018-16643: The functions ReadDCMImage, ReadPWPImage, ReadCALSImage, and ReadPICTImage did check the return value of the fputc function, which allowed remote attackers to cause a denial of service via a crafted image file (bsc#1107612)
• CVE-2018-16644: Added missing check for length in the functions ReadDCMImage and ReadPICTImage, which allowed remote attackers to cause a denial of service via a crafted image (bsc#1107609)
• CVE-2018-16645: Prevent excessive memory allocation issue in the functions ReadBMPImage and ReadDIBImage, which allowed remote attackers to cause a denial of service via a crafted image file (bsc#1107604)
