-Subject: [PATCH] Out of boundary access and endless loop in libXtst
-
-A lack of range checks in libXtst allows out of boundary accesses.
-The checks have to be done in-place here, because it cannot be done
-without in-depth knowledge of the read data.
-
-If XRecordStartOfData, XRecordEndOfData, or XRecordClientDied
-without a client sequence have attached data, an endless loop would
-occur. The do-while-loop continues until the current index reaches
-the end. But in these cases, the current index would not be
-incremented, leading to an endless processing.
