Unauthenticated memory corruption via oversized DELETE argument
Published May 16, 2025 · Updated May 16, 2025
Buffer overflow in the DELETE command handler in FreeFloat FTP Server 1.0 allows remote attackers to corrupt process memory. The handler processes an oversized DELETE command argument without enforcing the destination buffer's bounds, causing an out-of-bounds write. No authentication or user interaction is required; the write can crash the service or alter its execution, but the published record does not establish a specific code-execution outcome.
