PostgreSQL — свободная объектно-реляционная система управления базами данных.

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 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 8.0.0 and earlier allows local users to bypass the EXECUTE permission check for functions by using the CREATE AGGREGATE command.

The intagg contrib module for PostgreSQL 8.0.0 and earlier allows attackers to cause a denial of service (crash) via crafted arrays.

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 (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 uses the username for a salt when generating passwords, which makes it easier for remote attackers to guess passwords via a brute force attack.

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.

Buffer overflow in the date parser for PostgreSQL before 7.2.2 allows attackers to cause a denial of service and possibly execute arbitrary code via a long date string, aka a vulnerability "in handling long datetime input."

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.
