Service interruption via unterminated request buffer
Published Mar 26, 2025 · Updated Mar 26, 2025
Out-of-bounds read in Zhenwei Pi atophttpd 2.8.0 allows remote attackers to interrupt the service via a 1024-character HTTP request. When the req buffer receives exactly 1024 characters, its boundary handling leaves the string unterminated before subsequent parsing reads past the buffer. No authentication or user interaction is required; the published impact is a remotely induced service interruption, not data disclosure or modification.
