Base vector

AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H

Name of the Vulnerable Software and Affected Versions ImageMagick versions prior to 6.9.10-68 and 7.0.8-68

Description The issue arises from an improper call to AcquireVirtualMemory() and memset() in the WriteOnePNGImage() function of the PNG coder, allowing for an out-of-bounds write when PopShortPixel() is called. This could enable an attacker who supplies a specially crafted image to affect availability with a low impact to data integrity.

Recommendations For versions prior to 6.9.10-68 and 7.0.8-68, update to a version that includes the patch fixing the calls by adding 256 to rowbytes. At the moment, there is no information about additional mitigation measures.
