Vulnerabilidades

There is an illegal address access in the _nc_save_str function in alloc_entry.c in ncurses 6.0. It will lead to a remote denial of service attack.

There is an infinite loop in the next_char function in comp_scan.c in ncurses 6.0, related to libtic. A crafted input will lead to a remote denial of service attack.

In ncurses 6.0, 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 attack if the terminfo library code is used to process untrusted terminfo data.

In ncurses 6.0, there is an attempted 0xffffffffffffffff access in the append_acs function of tinfo/parse_entry.c. It could lead to a remote denial of service attack if the terminfo library code is used to process untrusted terminfo data.

In ncurses 6.0, there is a format string vulnerability in the fmt_entry function. A crafted input will lead to a remote arbitrary code execution attack.

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

Buffer overflow in ncurses 5.0, and the ncurses4 compatibility package as used in Red Hat Linux, allows local users to gain privileges, related to "routines for moving the physical cursor and scrolling."

Buffer overflow in ncurses library allows local users to execute arbitrary commands via long environmental information such as TERM or TERMINFO_DIRS.
