Vulnerability Title
N/A
Source: NVD (National Vulnerability Database)
Vulnerability Description
In iTerm2 through 3.6.9, displaying a .txt file can cause code execution via DCS 2000p and OSC 135 data, if the working directory contains a malicious file whose name is valid output from the conductor encoding path, such as a pathname with an initial ace/c+ substring, aka "hypothetical in-band signaling abuse." This occurs because iTerm2 accepts the SSH conductor protocol from terminal output that does not originate from a legitimate conductor session.

Vulnerability Description
iTerm2是George Nachman个人开发者的一款为Mac OS X编写的终端仿真程序。 iTerm2 3.6.9及之前版本存在安全漏洞，该漏洞源于显示.txt文件时可能通过DCS 2000p和OSC 135数据执行代码，因为iTerm2接受来自非合法conductor会话的终端输出的SSH conductor协议。
