Description
This security bulletin contains information about 4 vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2024-22252)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote user to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the XHCI USB controller. A remote attacker with administrative access to the guest OS can trigger a use-after-free error and execute arbitrary code on the host OS.
On ESXi, the exploitation is contained within the VMX sandbox whereas, on Workstation and Fusion, this may lead to code execution on the machine where Workstation or Fusion is installed.
2) Use-after-free (CVE-ID: CVE-2024-22253)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote user to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the UHCI USB controller. A remote attacker with administrative access to the guest OS can trigger a use-after-free error and execute arbitrary code on the host OS.
On ESXi, the exploitation is contained within the VMX sandbox whereas, on Workstation and Fusion, this may lead to code execution on the machine where Workstation or Fusion is installed.
3) Out-of-bounds write (CVE-ID: CVE-2024-22254)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:H/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 a boundary error when processing untrusted input. A local user with privileges within the VMX process can trigger an out-of-bounds write and escape sandbox restrictions.
4) Information disclosure (CVE-ID: CVE-2024-22255)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote user to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output in the UHCI USB controller. A remote user with administrative access to the guest OS can read memory from the vmx process.
