Ubuntu Security Notice USN-6398-1
September 27, 2023

minidlna vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 23.04
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS (Available with Ubuntu Pro)
- Ubuntu 16.04 LTS (Available with Ubuntu Pro)


Several security issues were fixed in ReadyMedia.

Software Description:
- minidlna: lightweight DLNA/UPnP-AV server targeted at embedded systems


It was discovered that ReadyMedia was vulnerable to DNS rebinding attacks.
A remote attacker could possibly use this issue to trick the local DLNA
server to leak information. This issue only affected Ubuntu 16.04 LTS,
Ubuntu 18.04 LTS, Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2022-26505)

It was discovered that ReadyMedia incorrectly handled certain HTTP requests
using chunked transport encoding. A remote attacker could possibly use this
issue to cause buffer overflows, resulting in out-of-bounds reads and writes.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 23.04:
   minidlna                        1.3.0+dfsg-2.2ubuntu0.1
