CVSS 3.1
6.1 mediumCVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:HCVE-2020-25664
Medium (6.1). EPSS 0.7% chance of exploitation in the next 30 days.
In WriteOnePNGImage() of the PNG coder at coders/png.c, an improper call to AcquireVirtualMemory() and memset() allows for an out-of-bounds write later when PopShortPixel() from MagickCore/quantum-private.h is called. The patch fixes the calls by adding 256 to rowbytes. An attacker who is able to supply a specially crafted image could affect availability with a low impact to data integrity. This flaw affects ImageMagick versions prior to 6.9.10-68 and 7.0.8-68.
