Detailsinfo

A vulnerability was found in ImageMagick 7.0.7-9 (Image Processing Software) and classified as critical. Affected by this issue is the function ReadWPGImage of the file coders/wpg.c of the component WPG Image Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The bug was discovered 11/04/2017. The weakness was presented 11/05/2017 (GitHub Repository). The advisory is shared for download at github.com. This vulnerability is handled as CVE-2017-16546 since 11/05/2017. The attack may be launched remotely. No form of authentication is required for exploitation. Successful exploitation requires user interaction by the victim. There are known technical details, but no exploit is available.

The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $0-$5k.
