CVE-2019-20797: An issue was discovered in e6y prboom-plus 2.5.1.5.

Security readout for executives and security teams

CVE-2019-20797 is a buffer overflow in prboom-plus 2.5.1.5 network packet handling. Affected clients or servers processing malicious UDP packets could crash or potentially be corrupted. The public record does not provide CVSS, CWE, confirmed exploitation, or complete affected-product metadata. Exposure is most likely where prboom-plus 2.5.1.5, or distro packages based on it, are installed and use network or multiplayer UDP functionality. Internet-facing game servers are the clearest concern; ordinary desktop installs may still be exposed when joining untrusted network sessions. Treat this as a targeted exposure cleanup, not a broad emergency, unless your environment hosts internet-facing prboom-plus services. Prioritize updating or isolating exposed servers and unmanaged desktop installs. Mitigation focus: Apply Fedora or openSUSE security updates where those packages are used.; Check upstream or distribution guidance for fixed prboom-plus package versions.; Disable prboom-plus network or multiplayer use where it is unnecessary..
