1701 | dialog /tmp File Race Condition dialog allows local users to overwrite arbitrary files via a symlink attack to gain privileges on the system. The dialog program creates lock-files in the /tmp directory insecurely. A local attacker could leverage this vulnerability to create a symbolic link in /tmp and overwrite or corrupt sensitive files owned by another user. |
