xorg-x11-server: Heap buffer overflow in DeviceFocusEvent and ProcXIQueryPointer

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, leadin...

xorg-x11-server: out-of-bounds memory read in RRChangeOutputProperty and RRChangeProviderProperty

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...

xorg-x11-server: out-of-bounds memory reads/writes in XKB button actions

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...

xorg-x11-server: SELinux context corruption

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...

xorg-x11-server: heap buffer overflow in XISendDeviceHierarchyEvent

A flaw was found in X.Org server. In the XISendDeviceHierarchyEvent function, it is possible to exceed the allocated array length when certain new device IDs are added to the xXIHierarchyInfo struct. This can trigger a heap buffer overflow condition, which may lead to an application crash or remo...

xorg-x11-server: Out-of-bounds write in XIChangeDeviceProperty/RRChangeOutputProperty

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 f...

xorg-x11-server: SELinux unlabeled GLX PBuffer

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...

xorg-x11-server: Heap buffer overread/data leakage in ProcXIPassiveGrabDevice

A heap-based buffer over-read vulnerability was found in the X.org server's ProcXIPassiveGrabDevice function. This issue occurs when byte-swapped length values are used in replies, potentially leading to memory leakage and segmentation faults, particularly when triggered by a client with a...

xorg-x11-server: Use-after-free in ProcRenderAddGlyphs

A use-after-free vulnerability was found in the ProcRenderAddGlyphs function of Xorg servers. This issue occurs when AllocateGlyph is called to store new glyphs sent by the client to the X server, potentially resulting in multiple entries pointing to the same non-refcounted glyphs. Consequently,...

Fedora 40 : xorg-x11-server-Xwayland (2024-01a9916e9e)

The remote Fedora 40 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2024-01a9916e9e advisory. xwayland 23.2.6 - CVE fix for CVE-2024-31080, CVE-2024-31081, CVE-2024-31083 Tenable has extracted the preceding description block directly from the...
