Description
Teeworlds up to and including 0.7.5 is vulnerable to a 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.
