Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Security restrictions bypass

EUVDB-ID: #VU50656

Risk: Low

CVSSv4.0: 1.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2021-20229

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote user to gain access to sensitive information.

The vulnerability exists due to application does not properly impose security restrictions. A user having a SELECT privilege on an individual column can craft a special query that returns all columns of the table. Additionally, a stored view that uses column-level privileges will have incomplete column-usage bitmaps. In installations that depend on column-level permissions for security, it is recommended to execute CREATE OR REPLACE on all user-defined views to force them to be re-parsed.

Mitigation

Update the affected packages.
dev-db/postgresql to version: 13.2

Vulnerable software versions
