Stack-based buffer overflow in the ncwriteentry function in tinfo/writeentry.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.

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

There is an illegal address access in the function ncreadentrysource() in progs/tic.c in ncurses 6.0 that might lead to a remote denial of service attack.

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

There is an illegal address access in the function dumpuses() in progs/dumpentry.c in ncurses 6.0 that might lead to a remote denial of service attack.

There is an illegal address access in the ncsafestrcat function in strings.c in ncurses 6.0 that will lead to a remote denial of service attack.

There is an illegal address access in the function postprocesstermcap() in parseentry.c in ncurses 6.0 that will lead to a remote denial of service attack.

There is an illegal address access in the fmtentry function in progs/dumpentry.c in ncurses 6.0 that might lead to a remote denial of service attack.

In ncurses 6.0, there is a NULL Pointer Dereference in the ncparseentry function of tinfo/parseentry.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 appendacs function of tinfo/parseentry.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 stack-based buffer overflow in the fmtentry function. A crafted input will lead to a remote arbitrary code execution attack.

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