Unknown vulnerability in cashout and possibly other functions in PostgreSQL 7.2.1 and earlier, and possibly later versions before 7.2.3, with unknown impact, based on an invalid integer input which is processed as a different data type, as demonstrated using cashout(2).

Buffer overflow in toascii for PostgreSQL 7.2.x, and 7.3.x before 7.3.4, allows remote attackers to execute arbitrary code.

Heap-based buffer overflow in the repeat() function for PostgreSQL before 7.2.2 allows attackers to execute arbitrary code by causing repeat() to generate a large string.

Vulnerability in the cashwords() 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.

PostgreSQL 7.2.1 and 7.2.2 allows local users to delete transaction log (pgclog) data and cause a denial of service (data loss) via the VACUUM command.

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.

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 readsqlconstruct function, (2) a large number of INTO variables in a SELECT statement being handled by the makeselectstmt function, (3) a large number of arbitrary variables in a SELECT statement being handled by the makeselectstmt function, and (4) a large number of INTO variables in a FETCH statement being handled by the makefetchstmt function, a different set of vulnerabilities than CVE-2005-0245.

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

Buffer overflows in (1) circlepoly, (2) pathencode and (3) pathadd (also incorrectly identified as pathaddr) 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.

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 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 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."

backend/parser/analyze.c in PostgreSQL 8.1.x before 8.1.5 allows remote authenticated users to cause a denial of service (daemon crash) via certain aggregate functions in an UPDATE statement, which are not properly handled during a "MIN/MAX index optimization."
