MySQL insecure temporary file creation (mysqlbug)


Shaun Colley reports that the script `mysqlbug' included with MySQL sometimes creates temporary files in an unsafe manner. As a result, an attacker may create a symlink in /tmp so that if another user invokes `mysqlbug' and quits without making any changes, an arbitrary file may be overwritten with the bug report template.
