Vulnerabilities 3
-
High 7.8
Libx11: integer overflow in xcreateimage() leading to a heap overflow
A vulnerability was found in libX11 due to an integer overflow within the XCreateImage() function. This flaw allows a local user to trigger an integer overflow and execute arbitrary code with elevated privileges.
-
Medium 6.5
Libx11: out-of-bounds memory access in _xkbreadkeysyms()
A vulnerability was found in libX11 due to a boundary condition within the _XkbReadKeySyms() function. This flaw allows a local user to trigger an out-of-bounds read error and read the contents of memory on the system.
-
Medium 5.5CVE-2023-43786 Public exploit
Libx11: stack exhaustion from infinite recursion in putsubimage()
A vulnerability was found in libX11 due to an infinite loop within the PutSubImage() function. This flaw allows a local user to consume all available system resources and cause a denial of service condition.
