    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.
