rxvt-unicode non-unix pty TTY Device Permission Weakness
Local Access Required Other
Loss of Confidentiality, Loss of Integrity
Exploit Unknown Vendor Verified

- 漏洞描述

rxvt-unicode contains a flaw that may allow an unauthorised malicious user to read from or write to tty terminal devices. The issue is present because on systems with non-unix pseudo terminals, permissions were not updated correctly. This left them as world-writable and world-readable, resulting in a loss of confidentiality and integrity.
