XBoard creates insecure temporary files
| xboard-tmpfile-insecure (13895) |  Medium Risk |
Description:
XBoard creates a temporary file in /tmp with an easily predictable file name, which could allow a local attacker to launch a symlink attack. A local attacker could create a symbolic link for a file in /tmp to an arbitrary file on the system, which would allow the attacker to create or overwrite files with privileges of another user.
Consequences:
File Manipulation
Remedy:
Upgrade to the latest version of XBoard (4.2.7 or later), available from the Tim Mann Web site. See References.
