CVSS v3.1 |
| PostgreSQL 8.1 and probably later versions, when the PL/pgSQL (plpgsql) language has been created, grants certain plpgsql privileges to the PUBLIC domain, which allows remote attackers to create and execute functions, as demonstrated by functions that perform local brute-force password guessing attacks, which may evade intrusion detection. |
| The core server component in PostgreSQL 8.4 before 8.4.1, 8.3 before 8.3.8, and 8.2 before 8.2.14 allows remote authenticated users to cause a denial of service (backend shutdown) by "re-LOAD-ing" libraries from a certain plugins directory. |
| PostgreSQL 7.4.x before 7.4.27, 8.0.x before 8.0.23, 8.1.x before 8.1.19, 8.2.x before 8.2.15, 8.3.x before 8.3.9, and 8.4.x before 8.4.2 does not properly manage session-local state during execution of an index function by a database superuser, which allows remote authenticated users to gain privileges via a table with crafted index functions, as demonstrated by functions that modify (1) search_path or (2) a prepared statement, a related issue to CVE-2007-6600 and CVE-2009-3230. |
| The postgresql-ocaml bindings 1.5.4, 1.7.0, and 1.12.1 for PostgreSQL libpq do not properly support the PQescapeStringConn function, which might allow remote attackers to leverage escaping issues involving multibyte character encodings. |
| The query planner in PostgreSQL before 8.0.11, 8.1 before 8.1.7, and 8.2 before 8.2.2 does not verify that a table is compatible with a "previously made query plan," which allows remote authenticated users to cause a denial of service (server crash) and possibly access database content via an "ALTER COLUMN TYPE" SQL statement, which can be leveraged to read arbitrary memory from the server. |
| PostgreSQL before 8.3.7, 8.2.13, 8.1.17, 8.0.21, and 7.4.25 allows remote authenticated users to cause a denial of service (stack consumption and crash) by triggering a failure in the conversion of a localized error message to a client-specified encoding, as demonstrated using mismatched encoding conversion requests. |
| Improper validation of type "oidvector" in PostgreSQL allows a database user to disclose a few bytes of server memory. We have not ruled out viability of attacks that arrange for presence of confidential information in disclosed bytes, but they seem unlikely. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected. |
| Missing validation of type of input in PostgreSQL intarray extension selectivity estimator function allows an object creator to execute arbitrary code as the operating system user running the database. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected. |
| Heap buffer overflow in PostgreSQL pgcrypto allows a ciphertext provider to execute arbitrary code as the operating system user running the database. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected. |
| Missing validation of multibyte character length in PostgreSQL text manipulation allows a database user to issue crafted queries that achieve a buffer overrun. That suffices to execute arbitrary code as the operating system user running the database. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected. |
| Heap buffer overflow in PostgreSQL pg_trgm allows a database user to achieve unknown impacts via a crafted input string. The attacker has limited control over the byte patterns to be written, but we have not ruled out the viability of attacks that lead to privilege escalation. PostgreSQL 18.1 and 18.0 are affected. |
| The intagg contrib module for PostgreSQL 8.0.0 and earlier allows attackers to cause a denial of service (crash) via crafted arrays. |
| Buffer overflow in gram.y for PostgreSQL 8.0.0 and earlier may allow attackers to execute arbitrary code via a large number of arguments to a refcursor function (gram.y), which leads to a heap-based buffer overflow, a different vulnerability than CVE-2005-0247. |
| 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. |
| PostgreSQL 7.3.x through 8.0.x gives public EXECUTE access to certain character conversion functions, which allows unprivileged users to call those functions with malicious values, with unknown impact, aka the "Character conversion vulnerability." |
| Buffer overflow in the ODBC driver for PostgreSQL before 7.2.1 allows remote attackers to cause a denial of service (crash). |
| PostgreSQL 7.2.1 and 7.2.2 allows local users to delete transaction log (pg_clog) data and cause a denial of service (data loss) via the VACUUM command. |
| Vulnerability in the cash_words() function for PostgreSQL 7.2 and earlier allows local users to cause a denial of service and possibly execute arbitrary code via a large negative argument, possibly triggering an integer signedness error or buffer overflow. |
| 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. |
| 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. |
