CVE-2017-16546: Canonical Ubuntu Linux

High severity, CVSS 8.8. EPSS: 2.2% chance of exploitation in the next 30 days.

The ReadWPGImage function in coders/wpg.c in ImageMagick 7.0.7-9 does not properly validate the colormap index in a WPG palette, which allows remote attackers to cause a denial of service (use of uninitialized data or invalid memory allocation) or possibly have unspecified other impact via a malformed WPG file.

Affected products

• Canonical Ubuntu Linux: version 14.04 only; version 16.04 only; version 17.10 only; version 18.04 only
• Debian Debian Linux: version 8.0 only; version 9.0 only
• ImageMagick ImageMagick: version 7.0.7-9 only
