title: private_address_check Ruby Gem Time-of-check Time-of-use race condition
private_address_check ruby gem before 0.5.0 is vulnerable to a time-of-check time-of-use (TOCTOU)
race condition due to the address the socket uses not being checked. DNS entries with a TTL of 0
can trigger this case where the initial resolution is a public address by the subsequent
resolution is a private address.
- ">= 0.5.0"
