jsdiff is a JavaScript text differencing implementation. Prior to versions 8.0.3, 5.2.2, 4.0.4, and 3.5.1, attempting to parse a patch whose filename headers contain the line break characters , , or can cause the method to enter an infinite loop. It then consumes memory without limit until the process crashes due to running out of memory.
