Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Permissions, Privileges, and Access Controls
EUVDB-ID: #VU40401
Risk: High
CVSSv4.0: 6.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2016-3065
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to #BASIC_IMPACT#.
The (1) brin_page_type and (2) brin_metapage_info functions in the pageinspect extension in PostgreSQL before 9.5.x before 9.5.2 allows attackers to bypass intended access restrictions and consequently obtain sensitive server memory information or cause a denial of service (server crash) via a crafted bytea value in a BRIN index page.
MitigationInstall update from vendor's website.

2) Security Features
EUVDB-ID: #VU40402
Risk: Medium
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2016-2193
CWE-ID:
CWE-254 - Security Features
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to manipulate data.
PostgreSQL before 9.5.x before 9.5.2 does not properly maintain row-security status in cached plans, which might allow attackers to bypass intended access restrictions by leveraging a session that performs queries as more than one role.
