Description Adam Mariš 2017-11-27 12:16:20 EST

Stack-based buffer overflow in the _nc_write_entry function in tinfo/write_entry.c in ncurses 6.0 allows attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted terminfo file, as demonstrated by tic.
