Description
This security bulletin contains information about 10 vulnerabilities.
1) Path traversal (CVE-ID: CVE-2020-5366)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote user to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences. A remote authenticated user can send a specially crafted HTTP request and read arbitrary files on the system.
2) 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.
3) 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.
4) 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.
5) Out-of-bounds read (CVE-ID: CVE-2020-3965)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the XHCI USB controller. A local attacker can trigger out-of-bounds read error and read contents of memory on the system.
6) Use-after-free (CVE-ID: CVE-2020-3963)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in PVNVRAM. A local attacker can read privileged information contained in hypervisor memory from a virtual machine.
7) Out-of-bounds read (CVE-ID: CVE-2020-3964)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the EHCI USB controller. A local attacker can trigger out-of-bounds read error and read contents of memory on the system.
8) Out-of-bounds read (CVE-ID: CVE-2020-3960)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in NVMe functionality. A local attacker can trigger out-of-bounds read error and read contents of memory on the system.
9) Memory leak (CVE-ID: CVE-2020-3959)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to perform denial of service (DoS) attack on the target system.
The vulnerability exists due memory leak in the VMCI module. A local user can force the application to leak memory and perform denial of service attack.
10) Out-of-bounds Write (CVE-ID: CVE-2020-10713)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a local attacker to compromise vulnerable system.
The vulnerability exists due to a "BootHole" issue. An attacker with physical access can install persistent and stealthy bootkits or malicious bootloaders, trigger out-of-bounds write and execute arbitrary code on the target system.
