    Posted By LinuxSecurity Advisories
    Vulnerabilities in the Oracle VM VirtualBox are fixed in version 6.1.16. An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this vulnerability which can lead to execute code in the context of the hypervisor. (CVE-2020-14872).

    Vulnerabilities in the Oracle VM VirtualBox are fixed in version 6.1.16.
    
    An attacker must first obtain the ability to execute high-privileged code on
    the target guest system in order to exploit this vulnerability which can lead
    to execute code in the context of the hypervisor. (CVE-2020-14872).
    
    An attacker must first obtain the ability to execute high-privileged code on
    the target guest system in order to exploit this vulnerability.
    The specific flaw exists within the shader_generate_main function. The issue
    results from the lack of proper validation of user-supplied data, which can
    result in a read past the end of an allocated buffer. An attacker can
    leverage this in conjunction with other vulnerabilities to execute code in
    the context of the hypervisor. (CVE-2020-14881).
    
    An attacker must first obtain the ability to execute high-privileged code on
    the target guest system in order to exploit this vulnerability.
    The specific flaw exists within the shader_record_register_usage function.
    The issue results from the lack of proper validation of user-supplied data,
    which can result in a type confusion condition. An attacker can leverage
    this in conjunction with other vulnerabilities to execute code in the context
    of the hypervisor. (CVE-2020-14884).
    
    An attacker must first obtain the ability to execute high-privileged code on
    the target guest system in order to exploit this vulnerability. The specific
    flaw exists within the shader_generate_main function. The issue results from
    the lack of proper validation of user-supplied data, which can result in a
    read past the end of an allocated buffer. An attacker can leverage this in
    conjunction with other vulnerabilities to execute code in the context of the
    hypervisor. (CVE-2020-14885).
    
    An attacker must first obtain the ability to execute high-privileged code on
    the target guest system in order to exploit this vulnerability.
    The specific flaw exists within the shader_skip_unrecognized function. The
    issue results from the lack of proper validation of user-supplied data, which
    can result in a read past the end of an allocated buffer. An attacker can
    leverage this in conjunction with other vulnerabilities to execute code in
    the context of the hypervisor. (CVE-2020-14886).
    
    An attacker must first obtain the ability to execute high-privileged code on
    the target guest system in order to exploit this vulnerability which can
    result in unauthorized access to critical data or complete access to all
    Oracle VM VirtualBox accessible data. (CVE-2020-14889).
    
    An attacker must first obtain the ability to execute high-privileged code on
    the target guest system in order to exploit this vulnerability which result
    in unauthorized ability to cause a hang or frequently repeatable crash
    (complete DOS) of Oracle VM VirtualBox. (CVE-2020-14892).
    
    Also this updated version has some bugfix (See upstream Changelog).
