UBUNTU-CVE-2026-29508: Buffer Overflow
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.

Event History
Frequently Asked Questions
Which deployments are exposed to this issue?
ReadyMedia (formerly MiniDLNA) versions 1.3.0 through 1.3.3 are affected. Exposure requires the service to monitor a directory containing a malicious DFF audio file.
What must an attacker be able to do to trigger the vulnerability?
An attacker must place a crafted DFF file with an oversized PROP chunk size in a directory monitored by ReadyMedia. The service can parse the file automatically through inotify monitoring.
How does the impact differ on hardened systems?
On builds without effective stack protections, exploitation may achieve remote code execution. On hardened builds with stack protections, the described outcome is denial of service.
