Details

It was discovered that PostgreSQL incorrectly tracked tables with row
security. A remote attacker could possibly use this issue to perform
forbidden reads and modifications. (CVE-2024-10976)

Jacob Champion discovered that PostgreSQL clients used untrusted server
error messages. An attacker that is able to intercept network
communications could possibly use this issue to inject error messages that
could be interpreted as valid query results. (CVE-2024-10977)

Tom Lane discovered that PostgreSQL incorrectly handled certain privilege
assignments. A remote attacker could possibly use this issue to view or
change different rows from those intended. (CVE-2024-10978)

Coby Abrams discovered that PostgreSQL incorrectly handled environment
variables. A remote attacker could possibly use this issue to execute
arbitrary code. (CVE-2024-10979)
