The version of postgresql95 installed on the remote host is prior to 9.5.23-1.81. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2020-1442 advisory.

    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 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 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 issue has been discovered in the PostgreSQL database system, which could result in privilege escalation.

For additional information please refer to the upstream announcement at https://www.postgresql.org/about/news/1960/

The version of PostgreSQL installed on the remote host is 9.4.x prior to 9.4.24, 9.5.x prior to 9.5.19, 9.6.x prior to 9.6.15, 10.x prior to 10.10, or 11.x prior to 11.5. It is, therefore, affected by multiple vulnerabilities :

  - An unspecified vulnerability that allows an attacker to execute arbitrary     SQL as the function's owner. (CVE-2019-10208)

  - An insecure password handling vulnerability exists in the     EnterpriseDB Windows intstaller due to use of a temporary file.
    An attack can exploit this to read the PostgreSQL superuser     password from the file. (CVE-2019-10210)

  - An arbitrary code execution vulnerability exists in libeay32.dll     due to use of a hard-coded configuration directory. An attacker     can exploit this to load and execute arbitrary code as the user     running a PostgreSQL server or client. (CVE-2019-10211)

The PostgreSQL project reports :

Versions Affected: 9.4 - 11

Given a suitable `SECURITY DEFINER` function, an attacker can execute arbitrary SQL under the identity of the function owner. An attack requires `EXECUTE` permission on the function, which must itself contain a function call having inexact argument type match. For example, `length('foo'::varchar)` and `length('foo')` are inexact, while `length('foo'::text)` is exact. As part of exploiting this vulnerability, the attacker uses `CREATE DOMAIN` to create a type in a `pg_temp` schema. The attack pattern and fix are similar to that for CVE-2007-2138.

Writing `SECURITY DEFINER` functions continues to require following the considerations noted in the documentation :

https://www.postgresql.org/docs/devel/sql-createfunction.html#SQL-CREA TEFUNCTION-SECURITY

Versions Affected: 11

In a database containing hypothetical, user-defined hash equality operators, an attacker could read arbitrary bytes of server memory.
For an attack to become possible, a superuser would need to create unusual operators. It is possible for operators not purpose-crafted for attack to have the properties that enable an attack, but we are not aware of specific examples.

An update of the postgresql package has been released.

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has postgresql packages installed that are affected by multiple vulnerabilities:

  - 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)

  - 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 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)

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2022:0181 advisory.

    Package updates are available for TencentOS Server 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:
    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-2019-10208:
    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-2020-14350:
    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-2019-10130:
    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.
