A buffer overflow was discovered in the URL-authentication backend of the Icecast before 2.4.4. If the backend is enabled, then any malicious HTTP client can send a request for that specific resource including a crafted header, leading to denial of service and potentially remote code execution.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
