Insecure directory permissions in RPM distribution for PostgreSQL allows local users to gain privileges by reading a plaintext password file.

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."

PostgreSQL stores usernames and passwords in plaintext in (1) pgshadow and (2) pgpwd, which allows attackers with sufficient privileges to gain access to databases.

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.

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.

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.

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."

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.

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 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 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.
