CVE-2026-29508

Summary

ReadyMedia versions 1.3.0–1.3.3 contain a stack-based buffer overflow (CWE-121) triggered by parsing a malicious DFF audio file with an oversized PROP chunk size, which is used unvalidated to allocate a stack array and read data into it, enabling remote code execution or denial of service.

Exploitability

Exploitation requires placing a crafted DFF file in a directory monitored by ReadyMedia; the attacker must have network access and valid credentials (low privilege sufficient) to trigger automatic parsing via inotify.

Blast radius

Successful exploitation allows remote code execution on the affected server, potentially compromising the host and any downstream services or data accessible to the service account.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade to ReadyMedia version 1.3.4 or later, which contains the official fix for this vulnerability.
