CVE-2020-19186

In ncurses 6.0, a format string vulnerability exists in the fmt_entry function. A crafted input can lead to remote arbitrary code execution.

In ncurses 6.0, there is a stack-based buffer overflow in the fmt_entry function. A crafted input can lead to remote arbitrary code execution.

A buffer overflow vulnerability was found in ncurses 6.1 in the _nc_find_entry function in tinfo/comp_hash.c:70. A remote attacker can cause a denial of service (DoS) by sending a crafted command.

In ncurses 6.1, a buffer overflow vulnerability in the postprocess_terminfo function in tinfo/parse_entry.c:997 allows a remote attacker to cause a denial of service via a crafted command.
