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).

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - 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)

  - 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)

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - A vulnerability was found in postgresql versions 11.x prior to 11.3. The Windows installer for BigSQL-
    supplied PostgreSQL does not lock down the ACL of the binary installation directory or the ACL of the data
    directory; it keeps the inherited ACL. In the default configuration, an attacker having both an
    unprivileged Windows account and an unprivileged PostgreSQL account can cause the PostgreSQL service
    account to execute arbitrary code. An attacker having only the unprivileged Windows account can read
    arbitrary data directory files, essentially bypassing database-imposed read access limitations. An
    attacker having only the unprivileged Windows account can also delete certain data directory files.
    (CVE-2019-10127)

  - A vulnerability was found in postgresql versions 11.x prior to 11.3. The Windows installer for
    EnterpriseDB-supplied PostgreSQL does not lock down the ACL of the binary installation directory or the
    ACL of the data directory; it keeps the inherited ACL. In the default configuration, this allows a local
    attacker to read arbitrary data directory files, essentially bypassing database-imposed read access
    limitations. In plausible non-default configurations, an attacker having both an unprivileged Windows
    account and an unprivileged PostgreSQL account can cause the PostgreSQL service account to execute
    arbitrary code. (CVE-2019-10128)

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

    - Rebase to upstream release 10.15       Resolves: CVE-2020-25695       Resolves: CVE-2020-25694       Resolves: CVE-2020-25696

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues 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)

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3972-1 advisory.

    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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

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.
