CVE-2026-29508 Details
Description
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.
A stack-based buffer overflow vulnerability has been identified in ReadyMedia (formerly MiniDLNA) versions 1.3.0 through 1.3.3. This vulnerability allows remote attackers to corrupt stack memory by crafting a malicious DFF audio file with an oversized PROP chunk size value. The unvalidated chunk size is used to allocate a variable-length stack array, into which file data is read. Attackers can place the crafted DFF file in a directory monitored by ReadyMedia, triggering automatic parsing via inotify. This exploitation can lead to remote code execution on unprotected builds or a denial-of-service condition on hardened builds with stack protections.
Users can update to ReadyMedia version 1.3.4 or later, where this vulnerability has been fixed. For ASUS RT-AX86U routers, the latest firmware version 3.0.0.4.388_24437 is available on the ASUS support website.
