Discussion

PostgreSQL Date Parser Buffer Overflow Vulnerability

PostgreSQL is prone to a buffer overflow in the date parser. The vulnerability is due to insufficient bounds checking of data passed to the date parser. This issue may potentially be exploited to corrupt sensitive regions of memory with attacker-supplied values.

Successful exploitation will enable an attacker to execute code in the content of the database server process. A denial of service may also be the result of exploitation attempts.
