Description
This security bulletin contains information about 6 vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2023-6816)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/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 within the DeviceFocusEvent and ProcXIQueryPointer functions. A local user can trigger a heap-based buffer overflow and execute arbitrary code on the target system.
2) Race condition (CVE-ID: CVE-2024-0229)
CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/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 race condition when reattaching to a different master device. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.
3) Input validation error (CVE-ID: CVE-2024-0408)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to incorrectly labeled GLX PBuffers. A local user can perform a denial of service (DoS) attack.
4) Resource management error (CVE-ID: CVE-2024-0409)
CWE-ID: CWE-399 - Resource Management Errors
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to perform a denial of service (DoS) attack.
