Description
This security bulletin contains information about 6 vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2020-3962)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in the SVGA device when processing SVGA DXInvalidateContext command. A local attacker can execute arbitrary code on the hypervisor from a virtual machine.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
2) Off-by-one (CVE-ID: CVE-2020-3969)
CWE-ID: CWE-193 - Off-by-one Error
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to an off-by-one error in SVGA device when processing SVGA3D commands. A local attacker can trigger an off-by-one error and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Out-of-bounds read (CVE-ID: CVE-2020-3970)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition in the Shader functionality. A local attacker can trigger out-of-bounds read error and cause a denial of service condition on the system.
4) Heap-based buffer overflow (CVE-ID: CVE-2020-3967)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to escalate privileges on the system.
The vulnerability exists due to a boundary error in EHCI controller. A local attacker can pass specially crafted data to the application, trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Out-of-bounds write (CVE-ID: CVE-2020-3968)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to escalate privileges on the system.
The vulnerability exists due to a boundary error when processing untrusted input in xHCI controller. A local attacker can trigger out-of-bounds write and execute arbitrary code on the target system.
6) Race condition (CVE-ID: CVE-2020-3966)
CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to escalate privileges on the system.
The vulnerability exists due to a race condition in the USB 2.0 controller (EHCI). A local attacker can exploit the race, leading to heap-overflow and execute arbitrary code on the system.
