Malicious Jiffle scripts can be executed by GeoServer, either as a rendering transformation in WMS dynamic styles or as a WPS process, that can enter an infinite loop to trigger denial of service.
The Jiffle language supports multiple loop constructs that will cause its code block to be continuously executed until a certain condition is met. The Jiffle runtime should be updated to throw an exception if the script exceeds a certain number of loop iterations.
This vulnerability allows attackers to conduct denial-of-service attacks.
This vulnerability can be mitigated by disabling WMS dynamic styling (see WMS Settings). If the WPS extension is installed, the Jiffle process must also be disabled to mitigate this vulnerability (see WPS Settings)
