xorg: xwayland: X.Org X server: Information disclosure or Denial of Service via out-of-bounds read in XKB modifier map handling

A flaw was found in the X.Org X server. This vulnerability, an out-of-bounds read, affects the XKB X Keyboard Extension modifier map handling. An attacker with access to the X11 server can exploit this by sending a malformed request, which causes the server to read beyond its intended memory...

freerdp: FreeRDP: Denial of Service via double free vulnerability during disconnect

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. This double free vulnerability occurs during the cleanup process when a remote desktop session disconnects. Specifically, if a title allocation fails, a pointer to an application window is freed but not removed fro...

freerdp: FreeRDP: Denial of service due to use-after-free vulnerability

A flaw was found in FreeRDP. A remote attacker could exploit a use-after-free vulnerability in the xfSetWindowMinMaxInfo function. This occurs when a freed window pointer is dereferenced because the main thread concurrently deletes a window while the Remote Desktop Protocol RAIL channel thread is...

xwayland: xorg: X.Org X server: Information disclosure and denial of service via out-of-bounds read in XKB geometry processing.

A flaw was found in the X.Org X server. This out-of-bounds read vulnerability in the XKB geometry processing, specifically within the CheckSetGeom and XkbAddGeomKeyAlias functions, allows an attacker to read uninitialized or out-of-bounds memory. An attacker with a connection to the X11 server,...
