libespeak-ng.so is vulnerable to Denial Of Service through Floating Point Exception. The vulnerability is due to the PeaksToHarmspect function within wavegen.c failing to check the wdata.pitch_env pointer before it is used. The function AdvanceParameters directly uses wdata.pitch_env without verifying if it is null or properly initialized, which results in Denial of Service.
