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...

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 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: PostgreSQL: Arbitrary code execution via plperl tied hash heap buffer overflow

A flaw was found in PostgreSQL. A heap buffer overflow vulnerability exists in the plperl component when returning a tied hash. This allows a function owner to execute arbitrary code as the operating system user running the database by providing a specially crafted function body. This could lead ...

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...

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...

CVE-2026-6669 Unbounded SCRAM iteration count causes CPU exhaustion in PgBouncer

Missing upper bound on the key derivation iteration count accepted during SCRAM authentication to a backend server in PgBouncer through 1.25.2 allows a malicious or compromised PostgreSQL backend to cause uncontrolled CPU consumption in PgBouncer. The resulting key derivation cannot be interrupte...

CVE-2026-6669

A flaw in PgBouncer (through version 1.25.2) allows a malicious or compromised PostgreSQL backend to cause uncontrolled CPU consumption due to a missing upper bound on the SCRAM authentication key derivation iteration count. Because the resulting key derivation cannot be interrupted in frontend b...

CVE-2026-6669

Missing upper bound on the key derivation iteration count accepted during SCRAM authentication to a backend server in PgBouncer through 1.25.2 allows a malicious or compromised PostgreSQL backend to cause uncontrolled CPU consumption in PgBouncer. The resulting key derivation cannot be interrupte...

postgresql: PostgreSQL: Arbitrary code execution via untrusted data inclusion in pg_dump

A vulnerability in PostgreSQL allows a malicious origin-server superuser to achieve client-side arbitrary code execution during a database restore. By injecting untrusted data into a pgdump export, the attacker can exploit the input expansion of the psql \restrict meta-command. When a victim...

postgresql: PostgreSQL: Stack buffer overflow via OUT parameter count manipulation

A flaw was found in PostgreSQL. An object creator can exploit a stack buffer overflow vulnerability within the argument name matching component. By manipulating the OUT parameter count, an attacker can write limited arbitrary bytes 0x0 and 0x1 to server memory, which may lead to unknown impacts...

Important: Red Hat Security Advisory: postgresql:15 security update

An update for the postgresql:15 module is now available for Red Hat Enterprise Linux 9.4 Update Services for SAP Solutions. 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 severi...

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: 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: Arbitrary code execution via long POSIX timezone abbreviation
