RHSA-2026:67280
Vulnerability from csaf_redhat - Published: 2026-09-14 11:20 - Updated: 2026-09-14 17:45A 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 requires the attacker to control both the server and the data being copied, or to leverage a coincidental error while controlling only the data.

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.
A flaw was found in PostgreSQL. An attacker with `pg_create_subscription` rights can exploit a SQL injection vulnerability in the `pg_createsubscriber` utility. This allows the attacker to execute arbitrary SQL commands with superuser privileges when `pg_createsubscriber` is next run, leading to potential compromise of the database system.
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 potentially allow an attacker to execute arbitrary code as the operating system user running the database.
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 operating system user running the database.
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 unauthorized insight into system memory.
A heap buffer overflow flaw was found in the PostgreSQL to_char(timestamptz) 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.
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 to unauthorized access and control over the database system.
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.
A flaw was found in PostgreSQL pg_stat_statements. A local attacker, specifically a query author, could exploit a heap buffer overflow vulnerability by crafting special queries containing array constants. This could allow the attacker to execute arbitrary code as the operating system user running the database, leading to a complete compromise of the database system.
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 user running the database.
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.
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.
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 pg_dump or psql inspect or export the object.
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 `levenshtein_less_equal()` SQL functions. This allows the user to execute arbitrary code as the operating system user running the database, potentially leading to full system compromise.
A flaw was found in PostgreSQL. An object creator can exploit a type confusion vulnerability in the `pg_restore_attribute_stats()` function. This flaw occurs due to the conflation of range and multirange values, allowing the attacker to execute arbitrary code as the operating system user running the database. This could lead to a complete compromise of the database system.
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 exploitation could lead to a complete compromise of the database system.
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 pg_dump export, the attacker can exploit the input expansion of the psql \restrict meta-command. When a victim processes this manipulated dump, the injected code executes with the privileges of the operating system account running the psql client.
A flaw was found in PostgreSQL pg_dump. 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 system user running pg_dump.

"details": "If upgrading to PostgreSQL 18.5 or later is not immediately possible, the pg_stat_statements extension can be disabled as a workaround. Remove \u0027pg_stat_statements\u0027 from the shared_preload_libraries parameter in postgresql.conf and restart the PostgreSQL service. This disables query statistics tracking but fully eliminates the attack surface for this vulnerability, as the heap buffer overflow exists exclusively within the pg_stat_statements query-normalization code path and is not reachable when the extension is not loaded. Additionally, limiting database access to trusted, vetted users reduces exposure, though it does not eliminate the risk for any authenticated user who can submit arbitrary queries.",

A low-privileged database user could achieve arbitrary code execution as the operating system user running the database. This risk is present only when the `fuzzystrmatch` extension is explicitly installed and utilized, as it is not enabled by default in Red Hat deployments. The flaw stems from an integer wraparound when processing extreme inputs to specific SQL functions.",

Alternatively, the `postgresql-fuzzystrmatch` package can be removed.

A type confusion flaw in the cursor lifecycle allows a low-privileged authenticated database user to execute arbitrary code as the operating system user running the database. This can lead to a complete compromise of the database system, making it a significant risk in typical Red Hat deployments where PostgreSQL instances are exposed to authenticated users.",
