Subject: [PATCH] Fix OOB read 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
|
