Description
The vulnerability allows a remote authenticated attacker to bypass security restrictions on the target system.
The weakness exists in the pg_catalog.pg_logfile_rotate() function due to improper Access Control List (ACL) restrictions as it does not follow the same ACLs as the pg_rorate_logfile function. A remote attacker can connect to the database and cause the target software to force log rotation, write log messages across arbitrary log files or cause the service to crash.
