[Morten Linderud]

Arch Linux Security Advisory ASA-202012-15
==========================================

Severity: High
Date    : 2020-12-09
CVE-ID  : CVE-2020-28926
Package : minidlna
Type    : arbitrary code execution
Remote  : Yes
Link    : https://security.archlinux.org/AVG-1321

Summary
=======

The package minidlna before version 1.3.0-1 is vulnerable to arbitrary
code execution.

Resolution
==========

Upgrade to 1.3.0-1.

# pacman -Syu "minidlna>=1.3.0-1"

The problem has been fixed upstream in version 1.3.0.

Workaround
==========

None.

Description
===========

ReadyMedia (aka MiniDLNA) before versions 1.3.0 allows remote code
execution. Sending a malicious UPnP HTTP request to the miniDLNA
service using HTTP chunked encoding can lead to a signedness bug
resulting in a buffer overflow in calls to memcpy/memmove.

Impact
======

An attacker on the local network can execute arbitrary code via a
malicious UPnP HTTP request.
