The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:1994-1 advisory.

  - A flaw was found in postgresql in versions before 13.3, before 12.7, before 11.12, before 10.17 and before     9.6.22. While modifying certain SQL array values, missing bounds checks let authenticated database users     write arbitrary bytes to a wide area of server memory. The highest threat from this vulnerability is to     data confidentiality and integrity as well as system availability. (CVE-2021-32027)

  - A flaw was found in postgresql. Using an INSERT ... ON CONFLICT ... DO UPDATE command on a purpose-crafted     table, an authenticated database user could read arbitrary bytes of server memory. The highest threat from     this vulnerability is to data confidentiality. (CVE-2021-32028)

  - A flaw was found in postgresql. Using an UPDATE ... RETURNING command on a purpose-crafted table, an     authenticated database user could read arbitrary bytes of server memory. The highest threat from this     vulnerability is to data confidentiality. (CVE-2021-32029)

Multiple security issues have been discovered in the PostgreSQL database system, which could result in the execution of arbitrary code or disclosure of memory content.

For Debian 9 stretch, these problems have been fixed in version 9.6.22-0+deb9u1.

We recommend that you upgrade your postgresql-9.6 packages.

For the detailed security status of postgresql-9.6 please refer to its security tracker page at:
