Synopsis

The remote Amazon Linux 2 host is missing a security update.

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-2019-17594)

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. (CVE-2019-17595)

Buffer Overflow vulnerability in one_one_mapping function in progs/dump_entry.c:1373 in ncurses 6.1 allows remote attackers to cause a denial of service via crafted command. (CVE-2020-19185)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
