Fixes the following security issues:
- CVE-2018-10754: 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 (REJECTED).
- CVE-2018-19211: In ncurses 6.1, there is a NULL pointer dereference at
function _nc_parse_entry in parse_entry.c that will lead to a denial of
service attack. The product proceeds to the dereference code path even
after a "dubious character `*' in name or alias field" detection.
- CVE-2018-19217: In ncurses, possibly a 6.x version, there is a NULL
pointer dereference at the function _nc_name_match that will lead to a
denial of service attack. NOTE: the original report stated version 6.1,
but the issue did not reproduce for that version according to the
maintainer or a reliable third-party.
- CVE-2019-17594: There is a heap-based buffer over-read in the
_nc_find_entry function in tinfo/comp_hash.c in the terminfo library in
ncurses before 6.1-20191012.
- CVE-2019-17595: There is a heap-based buffer over-read in the fmt_entry
function in tinfo/comp_hash.c in the terminfo library in ncurses before
6.1-20191012.
Ncurses upstream uses a fairly special way of releasing (security) bugfixes.
Approximately once a week an incremental .patch.gz is released, and once in
a while these incremental patches are bundled up to a bigger patch relative
to the current release in .patch.sh.bz2 format (a bzip2 compressed patch
with a small shell script prepended, luckily apply-patches can handle that),
and the relative patch files deleted.
For details of this process, see the upstream FAQ:
https://invisible-island.net/ncurses/ncurses.faq.html#applying_patches
Apply the latest .patch.sh.bz2 and incremental patches up to 20200118 to fix
a number of (security) issues. Notice that these patch files are NOT
available on the GNU mirrors.
The license file COPYING is updated with the new Copyright year (2019 ->
2020), so update the hash accordingly.
While we are at it, adjust the white space in the .hash file to match
sha256sum output for consistency.
