Description:
In ncurses before 6.1.20180414, there is a NULL Pointer Dereference in the _nc_parse_entry function of tinfo/parse_entry.c. It could lead to a remote denial of service if the terminfo library code is used to process untrusted terminfo data in which a use-name is invalid syntax. The product proceeds to the dereference code path even after a "dubious character `[' in name or alias field" detection.
