WinMTR 0.91 contains a denial of service vulnerability that allows attackers to crash the application by sending a malformed payload file containing a large buffer of repeated characters. Attackers can create a specially crafted input file with 238 bytes of data to trigger a buffer overflow condition that causes the application to crash.
