CVE-2021-3596: Debian Linux

Medium severity, CVSS 6.5. EPSS: 1.9% chance of exploitation in the next 30 days.

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.

Affected products

• Debian Debian Linux: version 9.0 only
• Fedoraproject Fedora: version 34 only
• ImageMagick ImageMagick: before 7.0.10-31 (fixed in 7.0.10-31)
• Red Hat Enterprise Linux: version 5.0 only; version 6.0 only; version 7.0 only
