Several vulnerabilities have been found in the PostgreSQL database system.

CVE-2020-25694

Peter Eisentraut found that database reconnections may drop options from the original connection, such as encryption, which could lead to information disclosure or a man-in-the-middle attack.

CVE-2020-25695

Etienne Stalmans reported that a user with permissions to create non-temporary objects in an schema can execute arbitrary SQL functions as a superuser.

CVE-2020-25696

Nick Cleaton found that the \gset command modified variables that control the psql behaviour, which could result in a compromised or malicious server executing arbitrary code in the user session.

For Debian 9 stretch, these problems have been fixed in version 9.6.20-0+deb9u1.

We recommend that you upgrade your postgresql-9.6 packages.

For the detailed security status of postgresql-9.6 please refer to its security tracker page at:

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2021:0017 advisory.

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

    CVE-2020-14349:
    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-2020-14350:
    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-2020-1720:
    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-2020-25694:
    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. 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-2020-25695:
    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-2020-25696:
    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.
