Teeworlds up to and including 0.7.5 is vulnerable to Buffer Overflow. A map
parser does not validate m_Channels value coming from a map file, leading
to a buffer overflow. A malicious server may offer a specially crafted map
that will overwrite client’s stack causing denial of service or code
execution.
