Technical details
The ExtractPostscript function in coders/wpg.c of GraphicsMagick fails to properly limit recursion depth when processing WPG files, allowing an attacker to craft a malicious file that triggers stack exhaustion. The vulnerability can be exploited remotely by sending a specially crafted WPG file to an application using the affected library. A fix is available in commit 627b5b1b2fc2.
