Does this matter?
Lower severity and a low EPSS score (0.99%). Track it; it rarely justifies an emergency change on its own.
Description
A flaw was found in Rust's Ring package. A panic may be triggered when overflow checking is enabled. In the QUIC protocol, this flaw allows an attacker to induce this panic by sending a specially crafted packet. It will likely occur unintentionally in 1 out of every 2**32 packets sent or received.
