| CVE-2004-0687 | 5 Openbsd, Redhat, Suse and 2 more | 6 Openbsd, Enterprise Linux, Network Satellite and 3 more | 2026-04-16 | N/A |
| Multiple stack-based buffer overflows in (1) xpmParseColors in parse.c, (2) ParseAndPutPixels in create.c, and (3) ParsePixels in parse.c for libXpm before 6.8.1 allow remote attackers to execute arbitrary code via a malformed XPM image file. | ||||
| CVE-2004-0688 | 5 Openbsd, Redhat, Suse and 2 more | 6 Openbsd, Enterprise Linux, Network Satellite and 3 more | 2026-04-16 | N/A |
| Multiple integer overflows in (1) the xpmParseColors function in parse.c, (2) XpmCreateImageFromXpmImage, (3) CreateXImage, (4) ParsePixels, and (5) ParseAndPutPixels for libXpm before 6.8.1 may allow remote attackers to execute arbitrary code via a malformed XPM image file. | ||||
| CVE-2004-0914 | 6 Gentoo, Lesstif, Redhat and 3 more | 8 Linux, Lesstif, Enterprise Linux and 5 more | 2026-04-16 | N/A |
| Multiple vulnerabilities in libXpm for 6.8.1 and earlier, as used in XFree86 and other packages, include (1) multiple integer overflows, (2) out-of-bounds memory accesses, (3) directory traversal, (4) shell metacharacter, (5) endless loops, and (6) memory leaks, which could allow remote attackers to obtain sensitive information, cause a denial of service (application crash), or execute arbitrary code via a certain XPM image file. NOTE: it is highly likely that this candidate will be SPLIT into other candidates in the future, per CVE's content decisions. | ||||
| CVE-2006-3740 | 3 Redhat, X.org, Xfree86 Project | 3 Enterprise Linux, X.org, Xfree86 X | 2026-04-16 | N/A |
| Integer overflow in the scan_cidfont function in X.Org 6.8.2 and XFree86 X server allows local users to execute arbitrary code via crafted (1) CMap and (2) CIDFont font data with modified item counts in the (a) begincodespacerange, (b) cidrange, and (c) notdefrange sections. | ||||
| CVE-2006-4447 | 1 X.org | 9 Emu-linux-x87-xlibs, X11r6, X11r7 and 6 more | 2026-04-16 | N/A |
| X.Org and XFree86, including libX11, xdm, xf86dga, xinit, xload, xtrans, and xterm, does not check the return values for setuid and seteuid calls when attempting to drop privileges, which might allow local users to gain privileges by causing those calls to fail, such as by exceeding a ulimit. | ||||
| CVE-2006-0197 | 1 X.org | 1 X.org | 2026-04-16 | N/A |
| The XClientMessageEvent struct used in certain components of X.Org 6.8.2 and earlier, possibly including (1) the X server and (2) Xlib, uses a "long" specifier for elements of the l array, which results in inconsistent sizes in the struct on 32-bit versus 64-bit platforms, and might allow attackers to cause a denial of service (application crash) and possibly conduct other attacks. | ||||
| CVE-2006-3739 | 3 Redhat, X.org, Xfree86 Project | 3 Enterprise Linux, X.org, Xfree86 X | 2026-04-16 | N/A |
| Integer overflow in the CIDAFM function in X.Org 6.8.2 and XFree86 X server allows local users to execute arbitrary code via crafted Adobe Font Metrics (AFM) files with a modified number of character metrics (StartCharMetrics), which leads to a heap-based buffer overflow. | ||||
| CVE-2006-0745 | 5 Mandrakesoft, Redhat, Sun and 2 more | 6 Mandrake Linux, Fedora Core, Solaris and 3 more | 2026-04-16 | N/A |
| X.Org server (xorg-server) 1.0.0 and later, X11R6.9.0, and X11R7.0 inadvertently treats the address of the geteuid function as if it is the return value of a call to geteuid, which allows local users to bypass intended restrictions and (1) execute arbitrary code via the -modulepath command line option or (2) overwrite arbitrary files via -logfile. | ||||
| CVE-2022-49737 | 1 X.org | 1 X Server | 2026-04-15 | 7.7 High |
| In X.Org X server 20.11 through 21.1.16, when a client application uses easystroke for mouse gestures, the main thread modifies various data structures used by the input thread without acquiring a lock, aka a race condition. In particular, AttachDevice in dix/devices.c does not acquire an input lock. | ||||
| CVE-2025-26601 | 3 Redhat, Tigervnc, X.org | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2026-04-06 | 7.8 High |
| A use-after-free flaw was found in X.Org and Xwayland. When changing an alarm, the values of the change mask are evaluated one after the other, changing the trigger values as requested, and eventually, SyncInitTrigger() is called. If one of the changes triggers an error, the function will return early, not adding the new sync object, possibly causing a use-after-free when the alarm eventually triggers. | ||||
| CVE-2025-26600 | 3 Redhat, Tigervnc, X.org | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2026-04-06 | 7.8 High |
| A use-after-free flaw was found in X.Org and Xwayland. When a device is removed while still frozen, the events queued for that device remain while the device is freed. Replaying the events will cause a use-after-free. | ||||
| CVE-2025-26599 | 3 Redhat, Tigervnc, X.org | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2026-04-06 | 7.8 High |
| An access to an uninitialized pointer flaw was found in X.Org and Xwayland. The function compCheckRedirect() may fail if it cannot allocate the backing pixmap. In that case, compRedirectWindow() will return a BadAlloc error without validating the window tree marked just before, which leaves the validated data partly initialized and the use of an uninitialized pointer later. | ||||
| CVE-2025-26598 | 3 Redhat, Tigervnc, X.org | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2026-04-06 | 7.8 High |
| An out-of-bounds write flaw was found in X.Org and Xwayland. The function GetBarrierDevice() searches for the pointer device based on its device ID and returns the matching value, or supposedly NULL, if no match was found. However, the code will return the last element of the list if no matching device ID is found, which can lead to out-of-bounds memory access. | ||||
| CVE-2025-26596 | 3 Redhat, Tigervnc, X.org | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2026-04-06 | 7.8 High |
| A heap overflow flaw was found in X.Org and Xwayland. The computation of the length in XkbSizeKeySyms() differs from what is written in XkbWriteKeySyms(), which may lead to a heap-based buffer overflow. | ||||
| CVE-2025-26595 | 3 Redhat, Tigervnc, X.org | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2026-04-06 | 7.8 High |
| A buffer overflow flaw was found in X.Org and Xwayland. The code in XkbVModMaskText() allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and would copy the data regardless of the size. | ||||
| CVE-2025-26594 | 3 Redhat, Tigervnc, X.org | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2026-04-06 | 7.8 High |
| A use-after-free flaw was found in X.Org and Xwayland. The root cursor is referenced in the X server as a global variable. If a client frees the root cursor, the internal reference points to freed memory and causes a use-after-free. | ||||
| CVE-2023-6377 | 4 Debian, Redhat, Tigervnc and 1 more | 11 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 8 more | 2026-03-24 | 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-2023-6816 | 4 Debian, Fedoraproject, Redhat and 1 more | 13 Debian Linux, Fedora, Enterprise Linux and 10 more | 2026-03-20 | 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-2023-1393 | 3 Fedoraproject, Redhat, X.org | 7 Fedora, Enterprise Linux, Rhel Aus and 4 more | 2026-01-22 | 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-2023-5380 | 4 Debian, Fedoraproject, Redhat and 1 more | 5 Debian Linux, Fedora, Enterprise Linux and 2 more | 2025-11-20 | 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. | ||||
