CVE-2021-3596 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. A NULL pointer dereference flaw was found in ImageMagick in versions prior to 7.0.10-31 in ReadSVGImage() in coders/svg.c. This issue is due to not checking the return value from libxml2's xmlCreatePushParserCtxt() and uses the value directly, which leads to a crash and segmentation fault.. EPSS estimates a 1.89% chance of exploitation in the next 30 days.
