A vulnerability has been found in GraphicsMagick 1.3.26 (Image Processing Software) and classified as critical. Affected by this vulnerability 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 null pointer dereference vulnerability. The CWE definition for the vulnerability is CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

The ReadWPGImage function in coders/wpg.c in GraphicsMagick 1.3.26 does not properly validate colormapped images, which allows remote attackers to cause a denial of service (ImportIndexQuantumType invalid write and application crash) or possibly have unspecified other impact via a malformed WPG image.

The bug was discovered 11/04/2017. The weakness was disclosed 11/05/2017 (Website). It is possible to read the advisory at hg.code.sf.net. This vulnerability is known as CVE-2017-16545 since 11/05/2017. The attack can be launched remotely. The exploitation doesn't need any form of authentication. It demands that the victim is doing some kind of user interaction. Technical details of the vulnerability are known, but there is no available exploit.
