|---|---|---|---|---|---|
| CVE-2024-0229 | 3 Fedoraproject, Redhat, X.org | 8 Fedora, Enterprise Linux, Enterprise Linux Aus and 5 more | 2024-11-23 | N/A | 7.8 HIGH |
| An out-of-bounds memory access flaw was found in the X.Org server. This issue can be triggered when a device frozen by a sync grab is reattached to a different master device. This issue may lead to an application crash, local privilege escalation (if the server runs with extended privileges), or remote code execution in SSH X11 forwarding environments. | |||||
| CVE-2024-0409 | 4 Fedoraproject, Redhat, Tigervnc and 1 more | 12 Fedora, Enterprise Linux, Enterprise Linux Desktop and 9 more | 2024-11-21 | N/A | 7.8 HIGH |
| A flaw was found in the X.Org server. The cursor code in both Xephyr and Xwayland uses the wrong type of private at creation. It uses the cursor bits type with the cursor as private, and when initiating the cursor, that overwrites the XSELINUX context. | |||||
| CVE-2024-0408 | 4 Fedoraproject, Redhat, Tigervnc and 1 more | 12 Fedora, Enterprise Linux, Enterprise Linux Desktop and 9 more | 2024-11-21 | N/A | 5.5 MEDIUM |
| 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 | 4 Debian, Fedoraproject, Redhat and 1 more | 7 Debian Linux, Fedora, Enterprise Linux Desktop and 4 more | 2024-11-21 | N/A | 9.8 CRITICAL |
| 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-2023-6478 | 4 Debian, Redhat, Tigervnc and 1 more | 6 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 3 more | 2024-11-21 | N/A | 7.6 HIGH |
| A flaw was found in xorg-server. A specially crafted request to RRChangeProviderProperty or RRChangeOutputProperty can trigger an integer overflow which may lead to a disclosure of sensitive information. | |||||
| CVE-2023-6377 | 4 Debian, Redhat, Tigervnc and 1 more | 6 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 3 more | 2024-11-21 | N/A | 7.8 HIGH |
| A flaw was found in xorg-server. Querying or changing XKB button actions such as moving from a touchpad to a mouse can result in out-of-bounds memory reads and writes. This may allow local privilege escalation or possible remote code execution in cases where X11 forwarding is involved. | |||||
| CVE-2023-5574 | 2 Redhat, X.org | 2 Enterprise Linux, X Server | 2024-11-21 | N/A | 7.0 HIGH |
| A use-after-free flaw was found in xorg-x11-server-Xvfb. This issue occurs in Xvfb with a very specific and legacy configuration (a multi-screen setup with multiple protocol screens, also known as Zaphod mode). If the pointer is warped from a screen 1 to a screen 0, a use-after-free issue may be triggered during shutdown or reset of the Xvfb server, allowing for possible escalation of privileges or denial of service. | |||||
| CVE-2023-5380 | 4 Debian, Fedoraproject, Redhat and 1 more | 5 Debian Linux, Fedora, Enterprise Linux and 2 more | 2024-11-21 | N/A | 4.7 MEDIUM |
| A use-after-free flaw was found in the xorg-x11-server. An X server crash may occur in a very specific and legacy configuration (a multi-screen setup with multiple protocol screens, also known as Zaphod mode) if the pointer is warped from within a window on one screen to the root window of the other screen and if the original window is destroyed followed by another window being destroyed. | |||||
| CVE-2023-5367 | 4 Debian, Fedoraproject, Redhat and 1 more | 12 Debian Linux, Fedora, Enterprise Linux and 9 more | 2024-11-21 | N/A | 7.8 HIGH |
| A out-of-bounds write flaw was found in the xorg-x11-server. This issue occurs due to an incorrect calculation of a buffer offset when copying data stored in the heap in the XIChangeDeviceProperty function in Xi/xiproperty.c and in RRChangeOutputProperty function in randr/rrproperty.c, allowing for possible escalation of privileges or denial of service. | |||||
| CVE-2023-43788 | 3 Fedoraproject, Redhat, X.org | 3 Fedora, Enterprise Linux, Libxpm | 2024-11-21 | N/A | 5.5 MEDIUM |
| A vulnerability was found in libXpm due to a boundary condition within the XpmCreateXpmImageFromBuffer() function. This flaw allows a local attacker to trigger an out-of-bounds read error and read the contents of memory on the system. | |||||
| CVE-2023-43787 | 3 Fedoraproject, Redhat, X.org | 3 Fedora, Enterprise Linux, Libx11 | 2024-11-21 | N/A | 7.8 HIGH |
| A vulnerability was found in libX11 due to an integer overflow within the XCreateImage() function. This flaw allows a local user to trigger an integer overflow and execute arbitrary code with elevated privileges. | |||||
| CVE-2023-43786 | 3 Fedoraproject, Redhat, X.org | 3 Fedora, Enterprise Linux, Libx11 | 2024-11-21 | N/A | 5.5 MEDIUM |
| A vulnerability was found in libX11 due to an infinite loop within the PutSubImage() function. This flaw allows a local user to consume all available system resources and cause a denial of service condition. | |||||
| CVE-2023-43785 | 3 Fedoraproject, Redhat, X.org | 3 Fedora, Enterprise Linux, Libx11 | 2024-11-21 | N/A | 6.5 MEDIUM |
| A vulnerability was found in libX11 due to a boundary condition within the _XkbReadKeySyms() function. This flaw allows a local user to trigger an out-of-bounds read error and read the contents of memory on the system. | |||||
| CVE-2023-3138 | 2 Redhat, X.org | 2 Enterprise Linux, Libx11 | 2024-11-21 | N/A | 7.5 HIGH |
| A vulnerability was found in libX11. The security flaw occurs because the functions in src/InitExt.c in libX11 do not check that the values provided for the Request, Event, or Error IDs are within the bounds of the arrays that those functions write to, using those IDs as array indexes. They trust that they were called with values provided by an Xserver adhering to the bounds specified in the X11 protocol, as all X servers provided by X.Org do. As the protocol only specifies a single byte for these values, an out-of-bounds value provided by a malicious server (or a malicious proxy-in-the-middle) can only overwrite other portions of the Display structure and not write outside the bounds of the Display structure itself, possibly causing the client to crash with this memory corruption. | |||||
| CVE-2023-1393 | 2 Fedoraproject, X.org | 2 Fedora, Xorg-server | 2024-11-21 | N/A | 7.8 HIGH |
| 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. | |||||
| CVE-2023-0494 | 3 Fedoraproject, Redhat, X.org | 18 Fedora, Enterprise Linux, Enterprise Linux Aus and 15 more | 2024-11-21 | N/A | 7.8 HIGH |
| A vulnerability was found in X.Org. This issue occurs due to a dangling pointer in DeepCopyPointerClasses that can be exploited by ProcXkbSetDeviceInfo() and ProcXkbGetDeviceInfo() to read and write into freed memory. This can lead to local privilege elevation on systems where the X server runs privileged and remote code execution for ssh X forwarding sessions. | |||||
| CVE-2022-4883 | 1 X.org | 1 Libxpm | 2024-11-21 | N/A | 8.8 HIGH |
| A flaw was found in libXpm. When processing files with .Z or .gz extensions, the library calls external programs to compress and uncompress files, relying on the PATH environment variable to find these programs, which could allow a malicious user to execute other programs by manipulating the PATH environment variable. | |||||
| CVE-2022-4283 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2024-11-21 | N/A | 7.8 HIGH |
| 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-2022-46344 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2024-11-21 | N/A | 8.8 HIGH |
| A vulnerability was found in X.Org. This security flaw occurs because the handler for the XIChangeProperty request has a length-validation issues, resulting in out-of-bounds memory reads and potential information disclosure. 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-2022-46343 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2024-11-21 | N/A | 8.8 HIGH |
| A vulnerability was found in X.Org. This security flaw occurs because the handler for the ScreenSaverSetAttributes request may write to memory after it has been freed. 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. | |||||
