CVE-2007-6427 7 Apple, Canonical, Debian and 4 more 11 Mac Os X, Ubuntu Linux, Debian Linux and 8 more 2020-11-20 9.3 HIGH N/A
The XInput extension in X.Org Xserver before 1.4.1 allows context-dependent attackers to execute arbitrary code via requests related to byte swapping and heap corruption within multiple functions, a different vulnerability than CVE-2007-4990.
CVE-2019-17624 1 X.org 1 X Server 2020-08-24 4.6 MEDIUM 7.8 HIGH
"" In X.Org X Server 1.20.4, there is a stack-based buffer overflow in the function XQueryKeymap. For example, by sending ct.c_char 1000 times, an attacker can cause a denial of service (application crash) or possibly have unspecified other impact. Note: It is disputed if the X.Org X Server is involved or if there is a stack overflow.
CVE-2011-4028 1 X.org 1 X Server 2020-08-24 1.2 LOW N/A
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-2011-4029 1 X.org 1 X Server 2020-08-24 1.9 LOW N/A
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-2011-4613 4 Canonical, Debian, Ubuntu and 1 more 4 Ubuntu Linux, Debian Linux, Linux and 1 more 2020-08-24 4.6 MEDIUM N/A
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-2013-1995 1 X.org 1 Libxi 2020-08-24 6.8 MEDIUM N/A
X.org libXi 1.7.1 and earlier allows X servers to trigger allocation of insufficient memory and a buffer overflow via vectors related to an unexpected sign extension in the XListInputDevices function.
CVE-2013-1984 1 X.org 1 Libxi 2020-08-24 6.8 MEDIUM N/A
Multiple integer overflows in X.org libXi 1.7.1 and earlier allow X servers to trigger allocation of insufficient memory and a buffer overflow via vectors related to the (1) XGetDeviceControl, (2) XGetFeedbackControl, (3) XGetDeviceDontPropagateList, (4) XGetDeviceMotionEvents, (5) XIGetProperty, (6) XIGetSelectedEvents, (7) XGetDeviceProperties, and (8) XListInputDevices functions.
CVE-2013-1998 1 X.org 1 Libxi 2020-08-24 6.8 MEDIUM N/A
Multiple buffer overflows in X.org libXi 1.7.1 and earlier allow X servers to cause a denial of service (crash) and possibly execute arbitrary code via crafted length or index values to the (1) XGetDeviceButtonMapping, (2) XIPassiveGrabDevice, and (3) XQueryDeviceState functions.
CVE-2018-14665 4 Canonical, Debian, Redhat and 1 more 9 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 6 more 2019-10-22 7.2 HIGH 6.6 MEDIUM
A flaw was found in xorg-x11-server before 1.20.3. An incorrect permission check for -modulepath and -logfile options when starting Xorg. X server allows unprivileged users with the ability to log in to the system via physical console to escalate their privileges and run arbitrary code under root privileges.
CVE-2017-2624 2 Debian, X.org 2 Debian Linux, Xorg-server 2019-10-09 1.9 LOW 7.0 HIGH
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-2017-12187 2 Debian, X.org 2 Debian Linux, Xorg-server 2019-10-09 7.5 HIGH 9.8 CRITICAL
xorg-x11-server before 1.19.5 was missing length validation in RENDER extension allowing malicious X client to cause X server to crash or possibly execute arbitrary code.
CVE-2017-12186 2 Debian, X.org 2 Debian Linux, Xorg-server 2019-10-09 7.5 HIGH 9.8 CRITICAL
xorg-x11-server before 1.19.5 was missing length validation in X-Resource extension allowing malicious X client to cause X server to crash or possibly execute arbitrary code.
CVE-2017-12185 2 Debian, X.org 2 Debian Linux, Xorg-server 2019-10-09 7.5 HIGH 9.8 CRITICAL
xorg-x11-server before 1.19.5 was missing length validation in MIT-SCREEN-SAVER extension allowing malicious X client to cause X server to crash or possibly execute arbitrary code.
CVE-2017-12184 2 Debian, X.org 2 Debian Linux, Xorg-server 2019-10-09 7.5 HIGH 9.8 CRITICAL
xorg-x11-server before 1.19.5 was missing length validation in XINERAMA extension allowing malicious X client to cause X server to crash or possibly execute arbitrary code.
CVE-2017-12183 2 Debian, X.org 2 Debian Linux, Xorg-server 2019-10-09 7.5 HIGH 9.8 CRITICAL
xorg-x11-server before 1.19.5 was missing length validation in XFIXES extension allowing malicious X client to cause X server to crash or possibly execute arbitrary code.
CVE-2017-12182 2 Debian, X.org 2 Debian Linux, Xorg-server 2019-10-09 7.5 HIGH 9.8 CRITICAL
xorg-x11-server before 1.19.5 was missing length validation in XFree86 DRI extension allowing malicious X client to cause X server to crash or possibly execute arbitrary code.
CVE-2017-12181 2 Debian, X.org 2 Debian Linux, Xorg-server 2019-10-09 7.5 HIGH 9.8 CRITICAL
xorg-x11-server before 1.19.5 was missing length validation in XFree86 DGA extension allowing malicious X client to cause X server to crash or possibly execute arbitrary code.
CVE-2017-12180 2 Debian, X.org 2 Debian Linux, Xorg-server 2019-10-09 7.5 HIGH 9.8 CRITICAL
xorg-x11-server before 1.19.5 was missing length validation in XFree86 VidModeExtension allowing malicious X client to cause X server to crash or possibly execute arbitrary code.

xorg-x11-server before 1.19.5 was vulnerable to integer overflow in (S)ProcXIBarrierReleasePointer functions allowing malicious X client to cause X server to crash or possibly execute arbitrary code.
CVE-2017-12178 2 Debian, X.org 2 Debian Linux, Xorg-server 2019-10-09 7.5 HIGH 9.8 CRITICAL
xorg-x11-server before 1.19.5 had wrong extra length check in ProcXIChangeHierarchy function allowing malicious X client to cause X server to crash or possibly execute arbitrary code.
