Doc Text:
A flaw was found in minidlna. This vulnerability allows a remote attacker to achieve arbitrary code execution or cause a Denial of Service (DoS) by placing a specially crafted DFF audio file into a directory monitored by the service. When processing the file, the application fails to validate an oversized chunk size, leading to a stack-based buffer overflow and memory corruption.

Description OSIDB Bzimport 2026-11-02 20:32:02 UTC 
ReadyMedia (formerly MiniDLNA) versions 1.3.0 through 1.3.3 contain a stack-based buffer overflow vulnerability that allows remote attackers to corrupt stack memory by crafting a malicious DFF audio file with an oversized PROP chunk size value that is used unvalidated to allocate a variable-length stack array and read file data into it. Attackers can place a crafted DFF file in a directory monitored by ReadyMedia to trigger automatic parsing via inotify, achieving remote code execution on unprotected builds or denial of service on hardened builds with stack protections.
