CVSS v3.1 |
| The tsearch2 module in PostgreSQL 7.4 through 8.0.x declares the (1) dex_init, (2) snb_en_init, (3) snb_ru_init, (4) spell_init, and (5) syn_init functions as "internal" even when they do not take an internal argument, which allows attackers to cause a denial of service (application crash) and possibly have other impacts via SQL commands that call other functions that accept internal arguments. |
| Multiple buffer overflows in gram.y for PostgreSQL 8.0.1 and earlier may allow attackers to execute arbitrary code via (1) a large number of variables in a SQL statement being handled by the read_sql_construct function, (2) a large number of INTO variables in a SELECT statement being handled by the make_select_stmt function, (3) a large number of arbitrary variables in a SELECT statement being handled by the make_select_stmt function, and (4) a large number of INTO variables in a FETCH statement being handled by the make_fetch_stmt function, a different set of vulnerabilities than CVE-2005-0245. |
| PostgreSQL 8.1.0 through 8.1.2 allows authenticated database users to gain additional privileges via "knowledge of the backend protocol" using a crafted SET ROLE to other database users, a different vulnerability than CVE-2006-0678. |
| PostgreSQL uses the username for a salt when generating passwords, which makes it easier for remote attackers to guess passwords via a brute force attack. |
| Buffer overflows in PostgreSQL 7.2 allow attackers to cause a denial of service and possibly execute arbitrary code via long arguments to the functions (1) lpad or (2) rpad. |
| Buffer overflows in the (1) TZ and (2) SET TIME ZONE enivronment variables for PostgreSQL 7.2.1 and earlier allow local users to cause a denial of service and possibly execute arbitrary code. |
| PostgreSQL 8.1.x before 8.1.4, 8.0.x before 8.0.8, 7.4.x before 7.4.13, 7.3.x before 7.3.15, and earlier versions allows context-dependent attackers to bypass SQL injection protection methods in applications via invalid encodings of multibyte characters, aka one variant of "Encoding-Based SQL Injection." |
| The intagg contrib module for PostgreSQL 8.0.0 and earlier allows attackers to cause a denial of service (crash) via crafted arrays. |
| Buffer overflows in (1) circle_poly, (2) path_encode and (3) path_add (also incorrectly identified as path_addr) for PostgreSQL 7.2.3 and earlier allow attackers to cause a denial of service and possibly execute arbitrary code, possibly as a result of an integer overflow. |
| PostgreSQL (pgsql) 7.4.x, 7.2.x, and other versions allows local users to load arbitrary shared libraries and execute code via the LOAD extension. |
| Buffer overflow in the ODBC driver for PostgreSQL before 7.2.1 allows remote attackers to cause a denial of service (crash). |
| Insecure directory permissions in RPM distribution for PostgreSQL allows local users to gain privileges by reading a plaintext password file. |
| The multibyte support in PostgreSQL 6.5.x with SQL_ASCII encoding consumes an extra character when processing a character that cannot be converted, which could remove an escape character from the query and make the application subject to SQL injection attacks. |
| PostgreSQL 8.0.x before 8.0.6 and 8.1.x before 8.1.2, when running on Windows, allows remote attackers to cause a denial of service (postmaster exit and no new connections) via a large number of simultaneous connection requests. |
| Untrusted data inclusion in pg_dump in PostgreSQL allows a malicious superuser of the origin server to inject arbitrary code for restore-time execution as the client operating system account running psql to restore the dump, via psql meta-commands. pg_dumpall is also affected. pg_restore is affected when used to generate a plain-format dump. This is similar to MySQL CVE-2024-21096. Versions before PostgreSQL 17.6, 16.10, 15.14, 14.19, and 13.22 are affected. |
| Improper neutralization of newlines in pg_dump in PostgreSQL allows a user of the origin server to inject arbitrary code for restore-time execution as the client operating system account running psql to restore the dump, via psql meta-commands inside a purpose-crafted object name. The same attacks can achieve SQL injection as a superuser of the restore target server. pg_dumpall, pg_restore, and pg_upgrade are also affected. Versions before PostgreSQL 17.6, 16.10, 15.14, 14.19, and 13.22 are affected. Versions before 11.20 are unaffected. CVE-2012-0868 had fixed this class of problem, but version 11.20 reintroduced it. |
| Buffer over-read in PostgreSQL GB18030 encoding validation allows a database input provider to achieve temporary denial of service on platforms where a 1-byte over-read can elicit process termination. This affects the database server and also libpq. Versions before PostgreSQL 17.5, 16.9, 15.13, 14.18, and 13.21 are affected. |
| Missing authorization in PostgreSQL CREATE STATISTICS command allows a table owner to achieve denial of service against other CREATE STATISTICS users by creating in any schema. A later CREATE STATISTICS for the same name, from a user having the CREATE privilege, would then fail. Versions before PostgreSQL 18.1, 17.7, 16.11, 15.15, 14.20, and 13.23 are affected. |
| Integer wraparound in multiple PostgreSQL libpq client library functions allows an application input provider or network peer to cause libpq to undersize an allocation and write out-of-bounds by hundreds of megabytes. This results in a segmentation fault for the application using libpq. Versions before PostgreSQL 18.1, 17.7, 16.11, 15.15, 14.20, and 13.23 are affected. |
| PostgreSQL optimizer statistics allow a user to read sampled data within a view that the user cannot access. Separately, statistics allow a user to read sampled data that a row security policy intended to hide. PostgreSQL maintains statistics for tables by sampling data available in columns; this data is consulted during the query planning process. Prior to this release, a user could craft a leaky operator that bypassed view access control lists (ACLs) and bypassed row security policies in partitioning or table inheritance hierarchies. Reachable statistics data notably included histograms and most-common-values lists. CVE-2017-7484 and CVE-2019-10130 intended to close this class of vulnerability, but this gap remained. Versions before PostgreSQL 17.6, 16.10, 15.14, 14.19, and 13.22 are affected. |
