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.
