OpenSSH Symbolic Link 'cookies' File Removal
Local Access Required Race Condition
Loss of Availability
Exploit Public

- 漏洞描述

OpenSSH versions 2.9 and earlier contains a flaw that, with X forwarding enabled, may allow a malicious local user to delete any file named 'cookies' via a symlink attack. The issue is triggered when X forwarding is enabled and the user is able to delete their cookies file and make a symlink linking the cookies file of another user to their temp directory. It is possible that the flaw may allow the users to delete the cookies files of others when logging out, resulting in a loss of availability of that file.
