xterm DECRQSS Device Control Request Status String code execution

xterm-decrqss-code-execution (47655) The risk level is classified as HighHigh Risk

Description:

xterm could allow a remote attacker to execute arbitrary code on the system, caused by an error in DECRQSS Device Control Request Status String escape sequence processing. By persuading a victim to open a specially-crafted text file containing certain escape sequences, an attacker could exploit this vulnerability to execute arbitrary code on the vulnerable system.
