"The remote Debian 11 / 12 host has a package installed that is affected by a vulnerability as referenced in the dsa-5434
advisory.
- 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. (CVE-2023-33476)
