CVE-2018-12599

In ImageMagick 7.0.8-3 Q16, ReadBMPImage and WriteBMPImage in coders/bmp.c allow attackers to cause an out of bounds write via a crafted file.

This update for ImageMagick fixes the following issues:

The following security vulnerabilities were fixed:

• CVE-2018-11625: Fixed heap-based buffer over-read in SetGrayscaleImage in the quantize.c file, which allowed remote attackers to cause buffer over-read via a crafted file. (bsc#1096200)
• CVE-2018-11624: Fixed a use-after-free issue in the ReadMATImage function in coders/mat.c. (bsc#1096203)
• CVE-2018-10805: Fixed several memory leaks in bgr.c, rgb.c, cmyk.c, gray.c, and ycbcr.c (bsc#1095812)
• CVE-2018-12600: The ReadDIBImage and WriteDIBImage functions allowed attackers to cause an out of bounds write via a crafted file (bsc#1098545).
• CVE-2018-12599: The ReadBMPImage and WriteBMPImage fucntions allowed attackers to cause an out of bounds write via a crafted file (bsc#1098546).

The following other changes were made:

• Fix -gamma issues in special cases. (bsc#1094745, bsc#1094742)

This update for ImageMagick fixes the following issues:

This update for ImageMagick fixes the following issues:

Security issues fixed:

• 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-2018-12600: ReadDIBImage and WriteDIBImage allowed attackers to cause an out of bounds write via a crafted file. (bsc#1098545)
• CVE-2018-12599: ReadBMPImage and WriteBMPImage allowed attackers to cause an out of bounds write via a crafted file. (bsc#1098546)

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.
