PostgreSQL 'to_char()' Function Buffer Overflow Vulnerability

PostgreSQL is prone to a buffer overflow vulnerability because it fails to perform adequate boundary checks.

An attacker can exploit this issue to execute arbitrary code in the context of the application. Failed exploit attempts likely result in denial-of-service conditions.

PostgreSQL versions 8.4, 9.1 and 9.4 are vulnerable.
