Vulnerabilidades

The infocmp command-line tool in ncurses before 6.5-20251213 has a stack-based buffer overflow in analyze_string in progs/infocmp.c.

A vulnerability has been found in GNU ncurses up to 6.5-20250322 and classified as problematic. This vulnerability affects the function postprocess_termcap of the file tinfo/parse_entry.c. The manipulation leads to stack-based buffer overflow. The attack needs to be approached locally. Upgrading to version…

Buffer Overflow vulnerability in _nc_find_entry in tinfo/comp_hash.c:70 in ncurses 6.1 allows remote attackers to cause a denial of service via crafted command.

Buffer Overflow vulnerability in postprocess_terminfo function in tinfo/parse_entry.c:997 in ncurses 6.1 allows remote attackers to cause a denial of service via crafted command.

Buffer Overflow vulnerability in fmt_entry function in progs/dump_entry.c:1116 in ncurses 6.1 allows remote attackers to cause a denial of service via crafted command.

Buffer Overflow vulnerability in fmt_entry function in progs/dump_entry.c:1100 in ncurses 6.1 allows remote attackers to cause a denial of service via crafted command.

Buffer Overflow vulnerability in _nc_find_entry function in tinfo/comp_hash.c:66 in ncurses 6.1 allows remote attackers to cause a denial of service via crafted command.

Buffer Overflow vulnerability in one_one_mapping function in progs/dump_entry.c:1373 in ncurses 6.1 allows remote attackers to cause a denial of service via crafted command.

ncurses before 6.4 20230408, when used by a setuid application, allows local users to trigger security-relevant memory corruption via malformed data in a terminfo database file that is found in $HOME/.terminfo or reached via the TERMINFO or TERM environment variable.

ncurses 6.3 before patch 20220416 has an out-of-bounds read and segmentation violation in convert_strings in tinfo/read_entry.c in the terminfo library.

An issue was discovered in ncurses through v6.2-1. _nc_captoinfo in captoinfo.c has a heap-based buffer overflow.

There is a heap-based buffer over-read in the fmt_entry function in tinfo/comp_hash.c in the terminfo library in ncurses before 6.1-20191012.

There is a heap-based buffer over-read in the _nc_find_entry function in tinfo/comp_hash.c in the terminfo library in ncurses before 6.1-20191012.

An issue was discovered in the ncurses crate through 5.99.0 for Rust. There are instr and mvwinstr buffer overflows because interaction with C functions is mishandled.

An issue was discovered in the ncurses crate through 5.99.0 for Rust. There are format string issues in printw functions because C format arguments are mishandled.

An issue was discovered in the pancurses crate through 0.16.1 for Rust. printw and mvprintw have format string vulnerabilities.

In ncurses, possibly a 6.x version, there is a NULL pointer dereference at the function _nc_name_match 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

In ncurses 6.1, there is a NULL pointer dereference at function _nc_parse_entry in parse_entry.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.

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.

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

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

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

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