Astra Linux – Vulnerability in xwayland, xorg-server

A buffer overflow vulnerability was discovered in X.Org and Xwayland. If the XkbChangeTypesOfKey function is called with a value of 0 for the “groups” parameter, it will resize the key symbol table to 0, but leave the key actions unchanged. If the same function is called later with a non-zero val...

Astra Linux – Vulnerability in xorg-server

In the X.Org X Server versions 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, which is known as a race condition. Specifically, the AttachDevice function in...

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,...

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

A heap-based buffer over-read vulnerability was found in the X.org server's ProcXIGetSelectedEvents 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...
