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...

php: NULL pointer dereference in SOAP apache:Map decoder with missing <value>

A flaw was found in PHP. When a PHP SOAP server has a typemap configured, the apache:Map decoding process checks the incorrect variable in case of a missing value element. This incorrect check leads to a NULL pointer dereference and allows a remote unauthenticated attacker to crash the PHP SOAP...
