-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.
