    =========================================
    
    Severity: Critical
    Date    : 2019-02-11
    CVE-ID  : CVE-2019-3813
    Package : spice
    Type    : arbitrary code execution
    Remote  : Yes
    Link    : https://security.archlinux.org/AVG-866
    
    Summary
    =======
    
    The package spice before version 0.14.0-3 is vulnerable to arbitrary
    code execution.
    
    Resolution
    ==========
    
    Upgrade to 0.14.0-3.
    
    # pacman -Syu "spice>=0.14.0-3"
    
    The problem has been fixed upstream but no release is available yet.
    
    Workaround
    ==========
    
    None.
    
    Description
    ===========
    
    Spice, versions 0.5.2 through 0.14.1, are vulnerable to an out-of-
    bounds read due to an off-by-one error in memslot_get_virt. This may
    lead to a denial of service, or, in the worst case, code-execution by
    unauthenticated attackers.
    
    Impact
    ======
    
    A remote, unauthenticated attacker might be able to crash the server,
    or even execute arbitrary code on said server.
