https://www.postgresql.org/about/news/1939/

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2021-9290 advisory.

  - A vulnerability was found in PostgreSQL versions 11.x up to excluding 11.3, 10.x up to excluding 10.8,     9.6.x up to, excluding 9.6.13, 9.5.x up to, excluding 9.5.17. PostgreSQL maintains column statistics for     tables. Certain statistics, such as histograms and lists of most common values, contain values taken from     the column. PostgreSQL does not evaluate row security policies before consulting those statistics during     query planning; an attacker can exploit this to read the most common values of certain columns. Affected     columns are those for which the attacker has SELECT privilege and for which, in an ordinary query, row-     level security prunes the set of rows visible to the attacker. (CVE-2019-10130)

  - A flaw was discovered in postgresql versions 9.4.x before 9.4.24, 9.5.x before 9.5.19, 9.6.x before     9.6.15, 10.x before 10.10 and 11.x before 11.5 where arbitrary SQL statements can be executed given a     suitable SECURITY DEFINER function. An attacker, with EXECUTE permission on the function, can execute     arbitrary SQL as the owner of the function. (CVE-2019-10208)

  - It was found that PostgreSQL versions before 12.4, before 11.9 and before 10.14 did not properly sanitize     the search_path during logical replication. An authenticated attacker could use this flaw in an attack     similar to CVE-2018-1058, in order to execute arbitrary SQL command in the context of the user used for     replication. (CVE-2020-14349)

  - PostgreSQL versions 10.x before 10.9 and versions 11.x before 11.4 are vulnerable to a stack-based buffer     overflow. Any authenticated user can overflow a stack-based buffer by changing the user's own password to     a purpose-crafted value. This often suffices to execute arbitrary code as the PostgreSQL operating system     account. (CVE-2019-10164)

  - A flaw was found in PostgreSQL's ALTER ... DEPENDS ON EXTENSION, where sub-commands did not perform     authorization checks. An authenticated attacker could use this flaw in certain configurations to perform     drop objects such as function, triggers, et al., leading to database corruption. This issue affects     PostgreSQL versions before 12.2, before 11.7, before 10.12 and before 9.6.17. (CVE-2020-1720)

  - It was found that some PostgreSQL extensions did not use search_path safely in their installation script.
    An attacker with sufficient privileges could use this flaw to trick an administrator into executing a     specially crafted script, during the installation or update of such extension. This affects PostgreSQL     versions before 12.4, before 11.9, before 10.14, before 9.6.19, and before 9.5.23. (CVE-2020-14350)

  - A flaw was found in PostgreSQL versions before 13.1, before 12.5, before 11.10, before 10.15, before     9.6.20 and before 9.5.24. If a client application that creates additional database connections only reuses     the basic connection parameters while dropping security-relevant parameters, an opportunity for a man-in-     the-middle attack, or the ability to observe clear-text transmissions, could exist. The highest threat     from this vulnerability is to data confidentiality and integrity as well as system availability.
    (CVE-2020-25694)

  - A flaw was found in the psql interactive terminal of PostgreSQL in versions before 13.1, before 12.5,     before 11.10, before 10.15, before 9.6.20 and before 9.5.24. If an interactive psql session uses \gset     when querying a compromised server, the attacker can execute arbitrary code as the operating system     account running psql. The highest threat from this vulnerability is to data confidentiality and integrity     as well as system availability. (CVE-2020-25696)

  - A flaw was found in PostgreSQL versions before 13.1, before 12.5, before 11.10, before 10.15, before     9.6.20 and before 9.5.24. An attacker having permission to create non-temporary objects in at least one     schema can execute arbitrary SQL functions under the identity of a superuser. The highest threat from this     vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-25695)

  - A vulnerability was found in postgresql versions 11.x prior to 11.3. Using a purpose-crafted insert to a     partitioned table, an attacker can read arbitrary bytes of server memory. In the default configuration,     any user can create a partitioned table suitable for this attack. (Exploit prerequisites are the same as     for CVE-2018-1052). (CVE-2019-10129)

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

The remote host is affected by the vulnerability described in GLSA-202003-03 (PostgreSQL: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in PostgreSQL. Please       review the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could possibly execute arbitrary code with the       privileges of the process, bypass certain client-side connection security       features, read arbitrary server memory, alter certain data or cause a       Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

New upstream release 11.4 Per release notes:
https://www.postgresql.org/docs/11/release-11-4.html

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of PostgreSQL installed on the remote host is 9.4.x prior to 9.4.22, 9.5.x prior to 9.5.17, 9.6.x prior to 9.6.13, 10.x prior to 10.8, or 11.x prior to 11.3. It is, therefore, affected by multiple vulnerabilities.

  - A remote code execution vulnerability exists in both, the BigSQL and the EnterpriseDB Windows installers due to the     installers not locking down the permissions of the PostgreSQL binary installation directory and the data directory.
    An authenticated, local attacker can exploit this, to cause the PostgreSQL service account to execute arbitrary     code.
    (CVE-2019-10127, CVE-2019-10128)

  - A memory disclosure vulnerability exists in the partition routing component. An authenticated, remote attacker can     exploit this, via the execution of a crafted INSERT statement to a partitioned table to disclose memory contents.
    (CVE-2019-10129)

  - A security bypass vulnerability exists in the core server. An authenticated, remote attacker can exploit this, via     the execution of a crafted SQL query with a leaky operator to disclose potentially sensitive information.
    (CVE-2019-10130)

It was discovered that PostgreSQL incorrectly handled partition routing. A remote user could possibly use this issue to read arbitrary bytes of server memory. This issue only affected Ubuntu 19.04.
(CVE-2019-10129)

Dean Rasheed discovered that PostgreSQL incorrectly handled selectivity estimators. A remote attacker could possibly use this issue to bypass row security policies. (CVE-2019-10130).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The PostgreSQL project reports :

Prior to this release, a user running PostgreSQL 11 can read arbitrary bytes of server memory by executing a purpose-crafted INSERT statement to a partitioned table.
