postgresql: PostgreSQL psql: Arbitrary command execution via untrusted data in COPY FROM STDIN

A flaw was found in PostgreSQL psql. During the COPY FROM STDIN operation, untrusted data can be mistakenly interpreted as psql commands if an error injection causes the command to fail prematurely. This could allow an attacker to achieve arbitrary command execution. Successful exploitation...

postgresql: PostgreSQL: Arbitrary code execution via integer wraparound in tsvector and tsquery functions

A flaw was found in PostgreSQL. An unprivileged database user can exploit an integer wraparound vulnerability in the tsvector and tsquery data type functions. By providing crafted large inputs, the server can be forced to undersize an allocation, leading to an out-of-bounds write. This could...

postgresql-fuzzystrmatch: PostgreSQL fuzzystrmatch: Arbitrary code execution via integer wraparound

A flaw was found in PostgreSQL fuzzystrmatch. A low-privileged database user can exploit an integer wraparound vulnerability by providing extreme inputs to the levenshtein or levenshteinlessequal SQL functions. This allows the user to execute arbitrary code as the operating system user running th...

postgresql: PostgreSQL pg_dump: Arbitrary code execution via crafted transform lists

A flaw was found in PostgreSQL pgdump. A heap buffer overflow vulnerability exists when processing long function transform lists. An authenticated object creator can exploit this by providing a specially crafted transform list. This allows the attacker to execute arbitrary code as the operating...

postgresql: PostgreSQL: Arbitrary code execution via long POSIX timezone abbreviation

A heap buffer overflow flaw was found in the PostgreSQL tochartimestamptz function. An attacker can exploit this by supplying an overly long POSIX timezone abbreviation to execute arbitrary code as the database's operating system user, potentially resulting in complete system compromise...

postgresql: PostgreSQL: Arbitrary code execution via type confusion in 'refint' module

A flaw was found in PostgreSQL. A type confusion vulnerability in the 'refint' module allows an object creator to execute arbitrary code as the operating system user running the database. This could lead to a complete compromise of the database server...

postgresql: PostgreSQL: Arbitrary code execution via type confusion with "internal" arguments

A type confusion vulnerability in PostgreSQL allows any user to execute arbitrary code as the database's operating system user by calling functions with mishandled "internal" data type arguments...

Important: Red Hat Security Advisory: postgresql:12 security update

An update for the postgresql:12 module is now available for Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support and Red Hat Enterprise Linux 8.4 Extended Update Support Long-Life Add-On. Red Hat Product Security has rated this update as having a security impact of Important. A...

postgresql: PostgreSQL: Arbitrary code execution via logical decoding plugin

A flaw was found in PostgreSQL. Missing authorization in PostgreSQL's logical decoding feature allows a non-superuser with REPLICATION privilege to load arbitrary files. This can lead to arbitrary code execution as the operating system account running the server...

postgresql: PostgreSQL: Arbitrary code execution via type confusion in cursor lifecycle

A flaw was found in PostgreSQL. This vulnerability, caused by type confusion in the 'portal'/cursor lifecycle, allows a user to execute arbitrary code as the operating system user running the database. This can occur by re-creating a cursor or other portal with different types. Successful...

postgresql: pltcl: plperl: PostgreSQL: Arbitrary code execution in 32-bit pltcl and plperl

A flaw was found in PostgreSQL. An integer wraparound vulnerability in 32-bit builds of pltcl and plperl allows an object creator to cause the server to undersize an allocation and write out-of-bounds via crafted function bodies. This can lead to arbitrary code execution as the operating system...

postgresql: PostgreSQL: Privilege escalation via SQL injection in EXTRACT() deparse

A SQL injection flaw in PostgreSQL's EXTRACT expression deparser allows an authenticated object owner to execute arbitrary SQL commands with superuser privileges. By defining a hostile database object, an attacker can achieve privilege escalation when deparsing tools like pgdump or psql inspect o...

postgresql: PostgreSQL: Arbitrary code execution via heap buffer overflow in regexp

A flaw was found in PostgreSQL. A heap buffer overflow vulnerability exists in the regexp component, which can be triggered by a query author providing text that does not pass encoding validation. This can lead to unanticipated data growth, allowing the attacker to execute arbitrary code as the...

postgresql: PostgreSQL: Information disclosure via type confusion in ctid selectivity estimator

A flaw was found in PostgreSQL. This vulnerability, stemming from a type confusion issue in the ctid data type selectivity estimator, could allow an authenticated object creator to access and potentially recover sensitive information from memory. By manipulating input, an attacker could gain...
