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_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).");
