| Doc Text: |
A flaw was found in vertx-pg-client. The binary array decoder does not enforce an upper bound on server-declared array dimensions during memory allocation. A malicious database server or an on-path attacker intercepting an unencrypted connection can exploit this flaw by sending a crafted message containing an excessively large dimension value. This forces the client application to attempt an excessive memory allocation, leading to a Denial of Service (DoS) through an out-of-memory crash.
