description

pgwire server versions 0.34.2 through 0.42.1 with TLS enabled can process pre-handshake cleartext as traffic from the TLS client. An attacker able to inject data before the TLS handshake finishes may cause statements to run where startup authentication is not enforced, or may disrupt authenticated connections otherwise.

mitigation

Upgrade the Rust pgwire package to version 0.42.2. Prioritize TLS-enabled servers, and restrict network paths where an attacker could intercept or inject connection traffic until upgraded.

fixed in 0.42.2
