Technical details

A stack-based buffer overflow exists in Pgpool-II's watchdog failover message processing (CWE-121) that can be triggered by sending malformed failover messages over the network without authentication. The vulnerability allows an attacker to write arbitrary-length data to the stack, corrupting memory and crashing the Pgpool-II process. Patches are available in versions 4.7.3, 4.6.8, 4.5.13, 4.4.18, and 4.3.21.
