xorg: xwayland: X.Org X server: Denial of Service via integer underflow in XKB compatibility map handling

A flaw was found in the X.Org X server. This integer underflow vulnerability, specifically in the XKB compatibility map handling, allows an attacker with local or remote X11 server access to trigger a buffer read overrun. This can lead to memory-safety violations and potentially a denial of servi...

Medium: capstone

Issue Overview: Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and prior, an unchecked vsnprintf return in SStreamconcat lets a malicious csoptmem.vsnprintf drive SStream's index negative or past the end, leading to a stack buffer underflow/overflow when the next write occurs. Comm...
