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.

A crash was reported in xterm prior to patch #366 when processing a specially crafted sequence of combining characters. The cause is an out of bounds write, which may be exploitable to cause arbitrary code execution.

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.

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.

xterm before 380 supports ReGIS reporting for character-set names even if they have unexpected characters (i.e., neither alphanumeric nor underscore), aka a pointer/overflow issue. This can only occur for xterm installations that are configured at compile time to use a certain experimental feature.

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.

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.

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.

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.
