postgresql: Reconnection can downgrade connection security settings

A flaw was found in postgresql. 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...

postgresql: Uncontrolled search path element in CREATE EXTENSION

A flaw was found in PostgreSQL, where some PostgreSQL extensions did not use the searchpath safely in their installation script. This flaw allows an attacker with sufficient privileges to trick an administrator into executing a specially crafted script during the extension's installation or updat...

Important: Red Hat Security Advisory: postgresql:10 security update

An update for the postgresql:10 module is now available for Red Hat Enterprise Linux 8.1 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating,...

postgresql: Selectivity estimators bypass row security policies

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 thi...

postgresql: Multiple features escape "security restricted operation" sandbox

A flaw was found in postgresql. 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...

postgresql: psql's \gset allows overwriting specially treated variables

A flaw was found in the psql interactive terminal of PostgreSQL. If an interactive psql session uses \gset when querying a compromised server, this flaw allows an attacker to execute arbitrary code as the operating system account running psql. The highest threat from this vulnerability is to...

postgresql: Uncontrolled search path element in logical replication

A flaw was found in PostgreSQL, where it did not properly sanitize the searchpath during logical replication. This flaw allows an authenticated attacker to use this flaw in an attack similar to CVE-2018-1058 to execute an arbitrary SQL command in the user's context for replication. The highest...

postgresql: Stack-based buffer overflow via setting a password

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: ALTER ... DEPENDS ON EXTENSION is missing authorization checks

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...

A flaw was found in postgresql. 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...

postgresql: TYPE in pg_temp executes arbitrary SQL during SECURITY DEFINER execution

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...
