NCurse v6.4-20230418 was discovered to contain a segmentation fault via the component _nc_wrap_entry().

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.

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 through Patch 370, when Sixel support is enabled, allows attackers to trigger a buffer overflow in set_sixel in graphics_sixel.c via crafted text.

xterm before Patch #366 allows remote attackers to execute arbitrary code or cause a denial of service (segmentation fault) via a crafted UTF-8 combining character sequence.

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 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.
