Package : minidlna
Version : 1.1.6+dfsg-1+deb9u2
CVE ID : CVE-2022-26505

An issue has been found in minidlna, a lightweight DLNA/UPnP-AV server
targeted at embedded systems. HTTP requests needed more checks to protect
against DNS rebinding, thus forbid a remote web server to exfiltrate
media files.

For Debian 9 stretch, this problem has been fixed in version
1.1.6+dfsg-1+deb9u2.

We recommend that you upgrade your minidlna packages.
