CVE-2022-45063

9.8 criticalEPSS 5.4%

Critical (9.8). EPSS 5.4% chance of exploitation in the next 30 days.

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.
