Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Security restrictions bypass

EUVDB-ID: #VU12652

Risk: Medium

CVSSv4.0: 5.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:H/SC:N/SI:H/SA:H/E:U/U:Green]

CVE-ID: CVE-2018-1115

CWE-ID: CWE-284 - Improper Access Control

Exploit availability: No

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.

Mitigation

Install update from vendor's website.
