CVE-2022-45063
9.8
CRITICAL · CVSS 3.1 · EPSS 5.4% (pctl 92)
In your normal cycle
Critical by CVSS (9.8), but no sign of active exploitation.
Description
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.
