> A memory overwriting bug was found in traffic_via which can potentially lead to remote code execution. In function decodeViaHeader in file traffic_via.cc, a call to strcat can potentially overwrite outside the bounds on the heap. For example, if the via header string is "abcde", the strcat concatenates a byte to the end and can corrupt the adjacent byte.
