-Patches copied from ncurses patch release 20170701:
-
-ftp://invisible-island.net/ncurses/6.0/ncurses-6.0-20170701.patch.gz
-
-Excerpt from patch release announcement:
-
- + add/improve checks in tic's parser to address invalid input
- (Redhat #1464684, #1464685, #1464686, #1464691).
- + alloc_entry.c, add a check for a null-pointer.
- + parse_entry.c, add several checks for valid pointers as well as
- one check to ensure that a single character on a line is not
- treated as the 2-character termcap short-name.
- + the fixes for Redhat #1464685 obscured a problem subsequently
- reported in Redhat #1464687; the given test-case was no longer
- reproducible. Testing without the fixes for the earlier reports
- showed a problem with buffer overflow in dump_entry.c, which is
- addressed by reducing the use of a fixed-size buffer.
