CVE-2021-43518

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.
