Summary

ZoneMinder before 1.38.4 contains static buffer overflow vulnerabilities in RemoteCameraHttp::GetResponse() that allow malicious HTTP cameras or intercepting attackers to overflow fixed-size buffers by sending oversized response headers. Attackers can send crafted HTTP responses with oversized status messages, Connection headers, Content-Type values, or multipart boundaries to corrupt parser state and crash the capture process or corrupt memory.
