NVD Description

Note: Versions mentioned in the description apply only to the upstream teeworlds package and not the teeworlds package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

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.
