CVE-2019-12976

ImageMagick versión 7.0.8-34 tiene una pérdida de memoria en la función ReadPCLImage en coders/pcl.c.

It was discovered that ImageMagick does not properly release acquired memory when some error conditions occur in the ReadPCLImage() function. Applications compiled against ImageMagick libraries that accept untrustworthy images may be exploited to use all available memory and make them crash. An attacker could abuse this flaw by providing a specially crafted image and cause a Denial of Service by using all available memory.

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 execute code with the privileges of the user invoking the program.
