The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:4433-1 advisory.

  - PostgreSQL Project reports:              Certain aggregate function calls receiving unknown-type     arguments could disclose bytes of server memory from the end of             the unknown-type value to     the next zero byte. One typically             gets an unknown-type value via a string literal having no     type             designation. We have not confirmed or ruled out viability of             attacks that     arrange for presence of notable, confidential             information in disclosed bytes.
    (CVE-2023-5868)

  - PostgreSQL Project reports:              While modifying certain SQL array values, missing     overflow checks let authenticated database users write             arbitrary bytes to a memory area that     facilitates             arbitrary code execution. Missing overflow checks also             let     authenticated database users read a wide area of             server memory. The CVE-2021-32027 fix covered     some             attacks of this description, but it missed others.            (CVE-2023-5869)

  - PostgreSQL Project reports:              Documentation says the pg_cancel_backend role cannot     signal a backend owned by a superuser. On the             contrary, it can signal background workers,     including             the logical replication launcher. It can signal             autovacuum workers and     the autovacuum launcher.             Signaling autovacuum workers and those two launchers     provides no meaningful exploit, so exploiting this             vulnerability requires a non-core extension     with a             less-resilient background worker. For example, a             non-core background worker     that does not auto-restart             would experience a denial of service with respect to     that particular background worker.

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2023:7714 advisory.

  - IN THE EXTENSION SCRIPT, a SQL Injection vulnerability was found in PostgreSQL if it uses @extowner@,     @extschema@, or @extschema:...@ inside a quoting construct (dollar quoting, '', or ). If an     administrator has installed files of a vulnerable, trusted, non-bundled extension, an attacker with     database-level CREATE privilege can execute arbitrary code as the bootstrap superuser. (CVE-2023-39417)

  - A memory disclosure vulnerability was found in PostgreSQL that allows remote users to access sensitive     information by exploiting certain aggregate function calls with 'unknown'-type arguments. Handling     'unknown'-type values from string literals without type designation can disclose bytes, potentially     revealing notable and confidential information. This issue exists due to excessive data output in     aggregate function calls, enabling remote users to read some portion of system memory. (CVE-2023-5868)

  - A flaw was found in PostgreSQL that allows authenticated database users to execute arbitrary code through     missing overflow checks during SQL array value modification. This issue exists due to an integer overflow     during array modification where a remote user can trigger the overflow by providing specially crafted     data. This enables the execution of arbitrary code on the target system, allowing users to write arbitrary     bytes to memory and extensively read the server's memory. (CVE-2023-5869)

  - A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers,     including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful     exploitation requires a non-core extension with a less-resilient background worker and would affect that     specific background worker only. This issue may allow a remote high privileged user to launch a denial of     service (DoS) attack. (CVE-2023-5870)
