CVE-2014-8101debianxorg-server+411y ago10-12-2014 15:00

The RandR extension in XFree86 4.2.0, X.Org X Window System (aka X11 or X) X11R6.7, and X.Org Server (aka xserver and xorg-server) before 1.16.3 allows remote authenticated users to cause a denial of service (out-of-bounds read or write) or possibly execute arbitrary code via a crafted length or index value to the (1) SProcRRQueryVersion, (2) SProcRRGetScreenInfo, (3) SProcRRSelectInput, or (4) SProcRRConfigureOutputProperty function.CVE-2022-2320debianxorg-server+64y ago01-09-2022 00:00

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.CVE-2022-2319debianxorg-server+64y ago01-09-2022 00:00

A flaw was found in the Xorg-x11-server. An out-of-bounds access issue can occur in the ProcXkbSetGeometry function due to improper validation of the request length.CVE-2022-4283debianxorg-server+93y ago14-12-2022 00:00

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-2022-46341debianxorg-server+83y ago14-12-2022 00:00

A vulnerability was found in X.Org. This security flaw occurs because the handler for the XIPassiveUngrab request accesses out-of-bounds memory when invoked with a high keycode or button code. 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-2022-46343debianxorg-server+83y ago14-12-2022 00:00

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.CVE-2022-46342debianxorg-server+83y ago14-12-2022 00:00

A vulnerability was found in X.Org. This security flaw occurs because the handler for the XvdiSelectVideoNotify request may write to memory after it has been freed. This issue can lead to local privileges elevation on systems where the X se CVE-2022-46340debianxorg-server+383y ago14-12-2022 00:00

A vulnerability was found in X.Org. This security flaw occurs becuase the swap handler for the XTestFakeInput request of the XTest extension may corrupt the stack if GenericEvents with lengths larger than 32 bytes are sent through a the XTestFakeInput request. 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. This issue does not affect systems where client and server use the same byte order.CVE-2022-46344debianxorg-server+83y ago14-12-2022 00:00

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-2022-49737chainguardxorg-server+111y ago16-03-2025 00:00

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-2022-3550debianxorg-server+94y ago17-10-2022 00:00

A vulnerability classified as critical was found in X.org Server. Affected by this vulnerability is the function _GetCountedString of the file xkb/xkb.c. The manipulation leads to buffer overflow. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-211051.CVE-2022-3551debianxorg-server+94y ago17-10-2022 00:00

A vulnerability, which was classified as problematic, has been found in X.org Server. Affected by this issue is the function ProcXkbGetKbdByName of the file xkb/xkb.c. The manipulation leads to memory leak. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability is VDB-211052.CVE-2022-3553chainguardxorg-server+44y ago17-10-2022 00:00

A vulnerability, which was classified as problematic, was found in X.org Server. This affects an unknown part of the file hw/xquartz/X11Controller.m of the component xquartz. The manipulation leads to denial of service. It is recommended to apply a patch to fix this issue. The identifier VDB-211053 was assigned to this vulnerability.CVE-2011-4029debianxorg-server+114y ago03-07-2012 19:00

The LockServer function in os/utils.c in X.Org xserver before 1.11.2 allows local users to change the permissions of arbitrary files to 444, read those files, and possibly cause a denial of service (removed execution permission) via a symlink attack on a temporary lock file.CVE-2011-4028debianxorg-server+1014y ago03-07-2012 19:00

The LockServer function in os/utils.c in X.Org xserver before 1.11.2 allows local users to determine the existence of arbitrary files via a symlink attack on a temporary lock file, which is handled differently if the file exists.CVE-2011-4613chainguardxorg-server+412y ago05-02-2014 19:00

The X.Org X wrapper (xserver-wrapper.c) in Debian GNU/Linux and Ubuntu Linux does not properly verify the TTY of a user who is starting X, which allows local users to bypass intended access restrictions by associating stdin with a file that is misinterpreted as the console TTY.CVE-2017-2624debianxorg-server+128y ago27-07-2018 18:00

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.CVE-2017-13721alpinexorg-server+69y ago09-10-2017 14:00

In X.Org Server (aka xserver and xorg-server) before 1.19.4, an attacker authenticated to an X server with the X shared memory extension enabled can cause aborts of the X server or replace shared memory segments of other X clients in the same session.CVE-2017-13723alpinexorg-server+69y ago09-10-2017 14:00

In X.Org Server (aka xserver and xorg-server) before 1.19.4, a local attacker authenticated to the X server could overflow a global buffer, causing crashes of the X server or potentially other problems by injecting large or malformed XKB related atoms and accessing them via xkbcomp.CVE-2017-10971debianxorg-server+49y ago06-07-2017 11:00

In the X.Org X server before 2017-06-19, a user authenticated to an X Session could crash or execute code in the context of the X Server by exploiting a stack overflow in the endianness conversion of X Events.
