"The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in
the openSUSE-SU-2021:1970-1 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)

  - postgresql: Memory disclosure in INSERT ... ON CONFLICT ... DO UPDATE (CVE-2021-32028)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
