ncurses: Local users can trigger security-relevant memory corruption via malformed data

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: Stack buffer overflow in fmt_entry function in progs/dump_entry.c:1116

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.

ncurses: Heap buffer overflow in fmt_entry function in progs/dump_entry.c:1100

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.

ncurses: Buffer overflow in _nc_find_entry function in tinfo/comp_hash.c:66

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.

ncurses: Heap buffer overflow in one_one_mapping function in progs/dump_entry.c:1373

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: heap-based buffer overflow in the fmt_entry function in tinfo/comp_hash.c

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.

ncurses: heap-based buffer overflow in the _nc_find_entry function in tinfo/comp_hash.c

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.

ncurses: heap-based buffer overflow in _nc_captoinfo() in captoinfo.c

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

MAWK 1.3.3-17 Stack-Based Buffer Overflow

MAWK 1.3.3-17 and prior contains a stack-based buffer overflow vulnerability that allows attackers to execute arbitrary code by exploiting inadequate boundary checks on user-supplied input. Attackers can craft malicious input that overflows the stack buffer and execute a return-oriented programming chain to spawn a shell with application privileges.

ncurses: ncurses: Buffer overflow vulnerability may lead to arbitrary code execution.

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

The default configuration of xterm on Debian GNU/Linux sid and possibly Ubuntu enables the allowWindowOps resource, which allows user-assisted attackers to execute arbitrary code or have unspecified other impact via escape sequences.

xterm: arbitrary command injection

CRLF injection vulnerability in xterm allows user-assisted attackers to execute arbitrary commands via LF (aka \n) characters surrounding a command name within a Device Control Request Status String (DECRQSS) escape sequence in a text file, a related issue to CVE-2003-0063 and CVE-2003-0071.

security flaw

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

security flaw

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."

CAN-2005-3120 lynx buffer overflow

Stack-based buffer overflow in the HTrjis function in Lynx 2.8.6 and earlier allows remote NNTP servers to execute arbitrary code via certain article headers containing Asian characters that cause Lynx to add extra escape (ESC) characters.

xterm: code execution via OSC 50 input sequences

xterm before 375 allows code execution via font ops, e.g., because an OSC 50 response may have Ctrl-g and therefore lead to command execution within the vi line-editing mode of Zsh. NOTE: font ops are not allowed in the xterm default configurations of some Linux distributions.

ncurses: segfaulting OOB read

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.
