The version of postgresql installed on the remote host is prior to 13.3-2. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2POSTGRESQL13-2023-003 advisory.

    A flaw was found in postgresql. 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)

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2021:0043 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2021-32027:
    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-2021-32028:
    ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when     announcing a new security problem. When the candidate has been publicized, the details for this candidate     will be provided.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of postgresql installed on the remote host is prior to 12.7-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2POSTGRESQL12-2023-004 advisory.

    A flaw was found in postgresql. 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.

    An information leak was discovered in postgresql in versions before 13.2, before 12.6 and before 11.11. A     user having UPDATE permission but not SELECT permission to a particular column could craft queries which,     under some circumstances, might disclose values from that column in error messages. An attacker could use     this flaw to obtain information stored in a column they are allowed to write but not read. (CVE-2021-3393)

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.

    Upgrade to version 12.7:

    - CVE-2021-32027: Fixed integer overflows in array subscripting calculations (bsc#1185924).
    - CVE-2021-32028: Fixed mishandling of junk columns in INSERT ... ON CONFLICT ... UPDATE target lists     (bsc#1185925).
    - CVE-2021-32029: Fixed possibly-incorrect computation of UPDATE ... RETURNING outputs for joined cross-     partition updates (bsc#1185926).

    - Don't use %_stop_on_removal, because it was meant to be private and got removed from openSUSE.
    %_restart_on_update is also private, but still supported and needed for now (bsc#1183168).
    - Re-enable build of the llvmjit subpackage on SLE, but it will only be delivered on PackageHub for now     (bsc#1183118).
    - Disable icu for PostgreSQL 10 (and older) on TW (bsc#1179945).
