CVE-2024-27304 – pgx SQL Injection via Protocol Message Size Overflow

https://notcve.org/view.php?id=CVE-2024-27304

pgx is a PostgreSQL driver and toolkit for Go. 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. The problem is resolved in v4.18.2 and v5.5.4. As a workaround, reject user input large enough to cause a single query or bind message to exceed 4 GB in size. • https://github.com/jackc/pgproto3/commit/945c2126f6db8f3bea7eeebe307c01fe92bca007 https://github.com/jackc/pgproto3/security/advisories/GHSA-7jwh-3vrq-q3m8 https://github.com/jackc/pgx/commit/adbb38f298c76e283ffc7c7a3f571036fea47fd4 https://github.com/jackc/pgx/commit/c543134753a0c5d22881c12404025724cb05ffd8 https://github.com/jackc/pgx/commit/f94eb0e2f96782042c96801b5ac448f44f0a81df https://github.com/jackc/pgx/security/advisories/GHSA-mrww-27vc-gghv https://access.redhat.com/security/cve/CVE-2024-27304 https://bugzilla.redhat.com/ • CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') CWE-190: Integer Overflow or Wraparound •
