Subject: [PATCH] Fix OOB crash for registerLocaleList
|
||
|
|
||
|
When the buffer size is equal to string size,
|
||
|
the func in icu just return warning U_STRING_NOT_TERMINATED_WARNING
|
||
|
which is a negative number, and U_FAILURE would fail if error number
|
||
|
greater than zero only.
|
||
|
|
||
|
This would cause non null terminated string passing into following funcs
|
||
|
and causing different types of crash
|
||
|
|
||
|
This fixes the previous partial fix.
