Astra Linux – Vulnerability in PostgresSQL 11

A vulnerability was discovered in PostgreSQL 12.2, allowing attackers to cause a denial of service by repeatedly sending SIGHUP signals. NOTE: This claim is disputed by the vendor, as untrusted users are unable to send SIGHUP signals; such signals can only be sent by a PostgreSQL superuser, a use...

Astra Linux – Vulnerability in PostgresSQL 11

Improper handling of newline characters in pgdump in PostgreSQL allows a user of the origin server to inject arbitrary code for execution during the restore process, through the client operating system account running psql. This occurs via psql meta-commands within a purpose-crafted object name...

Astra Linux – Vulnerability in PHP 7.3

In PHP versions 7.4.x below 7.4.30, 8.0.x below 8.0.20, and 8.1.x below 8.1.7, when using the Postgres database extension, providing invalid parameters to the parameterized query may cause PHP to attempt to free memory by using uninitialized data as pointers. This could lead to a RCE vulnerabilit...

Astra Linux – Vulnerability in PostgresSQL 11

A man-in-the-middle attacker can inject false responses to the client’s first few queries, despite the use of SSL certificate verification and encryption...

Astra Linux – Vulnerability in PostgresSQL 11

A flaw was discovered in the psql interactive terminal of PostgreSQL in versions prior to 13.1, prior to 12.5, prior to 11.10, prior to 10.15, prior to 9.6.20, and prior to 9.5.24. If an interactive psql session uses \gset when querying a compromised server, the attacker can execute arbitrary cod...

Astra Linux – Vulnerability in PostgresSQL 11

schemaelement defeats protective measures for search paths; It was discovered that certain database calls in PostgreSQL could allow an authenticated attacker with elevated database-level privileges to execute arbitrary code...

Astra Linux – Vulnerability in Sogo

Before version 5.12.7, when PostgreSQL was used, SOGo allowed SQL injection attacks...

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 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: 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: 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 '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-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 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 pg_stat_statements: Arbitrary code execution via heap buffer overflow

A flaw was found in PostgreSQL pgstatstatements. 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 t...

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: 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: 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...

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: 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...
