Title
Xorg-x11-server: selinux unlabeled glx pbuffer
Summary
A flaw was found in the X.Org server. The GLX PBuffer code does not call the XACE hook when creating the buffer, leaving it unlabeled. When the client issues another request to access that resource (as with a GetGeometry) or when it creates another resource that needs to access that buffer, such as a GC, the XSELINUX code will try to use an object that was never labeled and crash because the SID is NULL.

Title
Xorg-x11-server: heap buffer overflow in devicefocusevent and procxiquerypointer
Summary
A flaw was found in X.Org server. Both DeviceFocusEvent and the XIQueryPointer reply contain a bit for each logical button currently down. Buttons can be arbitrarily mapped to any value up to 255, but the X.Org Server was only allocating space for the device's particular number of buttons, leading to a heap overflow if a bigger value was used.

CVE-2023-1393 (GCVE-0-2023-1393)
Vulnerability from nvd – Published: 2023-03-30 00:00 – Updated: 2026-01-22 04:55
VLAI
Summary
A flaw was found in X.Org Server Overlay Window. A Use-After-Free may lead to local privilege escalation. If a client explicitly destroys the compositor overlay window (aka COW), the Xserver would leave a dangling pointer to that window in the CompScreen structure, which will trigger a use-after-free later.

Summary
A vulnerability was found in X.Org. This security flaw occurs because the XkbCopyNames function left a dangling pointer to freed memory, resulting in out-of-bounds memory access on subsequent XkbGetKbdByName requests.. This issue can lead to local privileges elevation on systems where the X server is running privileged and remote code execution for ssh X forwarding sessions.

CVE-2022-2320 (GCVE-0-2022-2320)
Vulnerability from nvd – Published: 2022-09-01 00:00 – Updated: 2024-08-03 00:32
VLAI
Summary
A flaw was found in the Xorg-x11-server. The specific flaw exists within the handling of ProcXkbSetDeviceInfo requests. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. This flaw allows an attacker to escalate privileges and execute arbitrary code in the context of root.
Severity
No CVSS data available.

CVE-2017-2624 (GCVE-0-2017-2624)
Vulnerability from nvd – Published: 2018-07-27 18:00 – Updated: 2024-08-05 14:02
VLAI
Summary
It was found that xorg-x11-server before 1.19.0 including uses memcmp() to check the received MIT cookie against a series of valid cookies. If the cookie is correct, it is allowed to attach to the Xorg session. Since most memcmp() implementations return after an invalid byte is seen, this causes a time difference between a valid and invalid byte, which could allow an efficient brute force attack.
Severity
5.9 (Medium)

CVE-2024-0408 (GCVE-0-2024-0408)

Title
Xorg-x11-server: selinux unlabeled glx pbuffer
Summary
A flaw was found in the X.Org server. The GLX PBuffer code does not call the XACE hook when creating the buffer, leaving it unlabeled. When the client issues another request to access that resource (as with a GetGeometry) or when it creates another resource that needs to access that buffer, such as a GC, the XSELINUX code will try to use an object that was never labeled and crash because the SID is NULL.

CVE-2023-6816 (GCVE-0-2023-6816)

Title
Xorg-x11-server: heap buffer overflow in devicefocusevent and procxiquerypointer
Summary
A flaw was found in X.Org server. Both DeviceFocusEvent and the XIQueryPointer reply contain a bit for each logical button currently down. Buttons can be arbitrarily mapped to any value up to 255, but the X.Org Server was only allocating space for the device's particular number of buttons, leading to a heap overflow if a bigger value was used.

CVE-2023-1393 (GCVE-0-2023-1393)
Vulnerability from cvelistv5 – Published: 2023-03-30 00:00 – Updated: 2026-01-22 04:55
VLAI
Summary
A flaw was found in X.Org Server Overlay Window. A Use-After-Free may lead to local privilege escalation. If a client explicitly destroys the compositor overlay window (aka COW), the Xserver would leave a dangling pointer to that window in the CompScreen structure, which will trigger a use-after-free later.
Severity
7.8 (High)
SSVC
Exploitation: none
Automatable: no
Technical Impact: total

Summary
A vulnerability was found in X.Org. This security flaw occurs because the XkbCopyNames function left a dangling pointer to freed memory, resulting in out-of-bounds memory access on subsequent XkbGetKbdByName requests.. This issue can lead to local privileges elevation on systems where the X server is running privileged and remote code execution for ssh X forwarding sessions.

Vulnerability from cvelistv5 – Published: 2022-09-01 00:00 – Updated: 2024-08-03 00:32
VLAI
Summary
A flaw was found in the Xorg-x11-server. The specific flaw exists within the handling of ProcXkbSetDeviceInfo requests. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. This flaw allows an attacker to escalate privileges and execute arbitrary code in the context of root.
Severity
No CVSS data available.

CVE-2017-2624 (GCVE-0-2017-2624)
Vulnerability from cvelistv5 – Published: 2018-07-27 18:00 – Updated: 2024-08-05 14:02
VLAI
Summary
It was found that xorg-x11-server before 1.19.0 including uses memcmp() to check the received MIT cookie against a series of valid cookies. If the cookie is correct, it is allowed to attach to the Xorg session. Since most memcmp() implementations return after an invalid byte is seen, this causes a time difference between a valid and invalid byte, which could allow an efficient brute force attack.

Since most memcmp() implementations return after an invalid byte is seen, this causes a time difference between a valid and invalid byte, which could allow an efficient brute force attack."
