| Doc Text: |
A flaw was found in the DataRow.Decode function within the github.com/jackc/pgproto3/v2 component. A malicious or compromised PostgreSQL server can exploit this by sending a DataRow message containing a negative field length. This improper validation of field lengths leads to a "slice bounds out of range panic", resulting in a Denial of Service (DoS) for the affected application.
