Vulnerabilidades

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."

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 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.

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.

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 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 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.

libnss-pgsql in nss-pgsql 0.9.0 and earlier allows remote attackers to execute arbitrary SQL queries by inserting SQL code into an HTTP request.

nss_postgresql 0.6.1 and before allows a remote attacker to execute arbitrary SQL queries by inserting SQL code into an HTTP request.

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

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