CVE-2022-45063

CRITICAL

xterm < 375 - Remote Code Execution via Font Operations

Title source: llm
STIX 2.1

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.
