Description

Impact

SQL injection can occur if an attacker can cause a single query or bind message to exceed 4 GB in size. An integer overflow in the calculated message size can cause the one large message to be sent as multiple messages under the attacker's control.

Patches

The problem is resolved in v2.3.3

Workarounds

Reject user input large enough to cause a single query or bind message to exceed 4 GB in size.

CWEs

  • CWE-89 · Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
  • CWE-190 · Integer Overflow or Wraparound
