Score breakdown

ReadyMedia (MiniDLNA) versions from 1.1.15 up to 1.3.2 is vulnerable to Buffer Overflow. The vulnerability is caused by incorrect validation logic when handling HTTP requests using chunked transport encoding. This results in other code later using attacker-controlled chunk values that exceed the length of the allocated buffer, resulting in out-of-bounds read/write.
