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.
Accelerate Framework. A memory consumption issue was addressed with improved memory handling.
Accounts. A privacy issue was addressed with improved private data redaction for log entries.
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 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.
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.
Buffer overflow in ncurses library allows local users to execute arbitrary commands via long environmental information such as TERM or TERMINFODIRS.
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."
Accelerate Framework. A memory consumption issue was addressed with improved memory handling.
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 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.
DISPUTED In ncurses, possibly a 6.x version, there is a NULL pointer dereference at the function ncnamematch that will lead to a denial of service attack. NOTE: the original report stated version 6.1, but the issue did not reproduce for that version according to the maintainer or a reliable third-party.

GNU ncurses could allow a remote attacker to obtain sensitive information, caused by a heap-based buffer over-read in the fmtentry function in tinfo/comphash.c in the terminfo library. By persuading a victim to open a specially-crafted file, an attacker could exploit this vulnerability to obtain sensitive information.
In ncurses 6.1, there is a NULL pointer dereference at function ncparseentry in parseentry.c that will lead to a denial of service attack. The product proceeds to the dereference code path even after a "dubious character ' in name or alias field" detection.
GNU ncurses could allow a remote attacker to obtain sensitive information, caused by a heap-based buffer over-read in the ncfindentry function in tinfo/comphash.c in the terminfo library. By persuading a victim to open a specially-crafted file, an attacker could exploit this vulnerability to obtain sensitive information.
