Open Source Vulnerabilities SUSE-SU-2018:3269-1

This update for GraphicsMagick fixes the following security issue: - CVE-2018-16750: Prevent memory leak in the formatIPTCfromBuffer function (bsc#1108283) - 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-2018-16640: Prevent memory leak in the function ReadOneJNGImage (bsc#1107619). - 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-2018-16643: 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). - CVE-2018-18024: Fixed an infinite loop in the ReadBMPImage function of the coders/bmp.c file. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted bmp file. (bsc#1111069) - CVE-2018-18016: Fixed a memory leak in WritePCXImage (bsc#1111072). - CVE-2018-17965: Fixed a memory leak in WriteSGIImage (bsc#1110747). - CVE-2018-17966: Fixed a memory leak in WritePDBImage (bsc#1110746). - CVE-2018-16749: A missing NULL check in ReadOneJNGImage allowed remote attackers to cause a denial of service (WriteBlob assertion failure and application exit) via a crafted file.
