Descriptions
A race condition exists in the Tang server functionality for key generation and key rotation. This flaw results in a small time window where Tang private keys become readable by other processes on the same host.
Brian McDermott discovered that Tang incorrectly handled permissions when creating/rotating keys. A local attacker could possibly use this issue to read the keys.
