Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Permissions, Privileges, and Access Controls
EUVDB-ID: #VU20003
Risk: Low
CVSSv3.1: 3.3 [CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-10208
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to escalate privileges on the system.
The vulnerability exists due to way PostreSQL processes SECURITY DEFINER functions. A privileged attacker with EXECUTE permission, which must itself contain a function call having inexact argument type match, can execute arbitrary SQL query under the identity of the function owner.
Install updates from vendor's website.
Vulnerable software versionsPostgreSQL: 9.4.0 - 11.4

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote authenticated privileged user via the Internet.
How the attacker can exploit this vulnerability?
The attacker would have to send a specially crafted request to the affected application in order to exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Information disclosure
EUVDB-ID: #VU20004
Risk: Low
CVSSv3.1: 2.7 [CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-10209
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to way PostgreSQL processes user-defined hash equality operators. A remote attacker can under certain circumstances read arbitrary bytes from server memory.
Note, exploitation of this vulnerability requires a superuser to create unusual operators.
MitigationInstall updates from vendor's website.
Vulnerable software versionsPostgreSQL: 11.0 - 11.4

3) Unprotected storage of credentials
EUVDB-ID: #VU20005
Risk: Low
CVSSv3.1: 2.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CWE-ID:
CWE-256 - Unprotected Storage of Credentials
Exploit availability: No
DescriptionInstall updates from vendor's website.
Vulnerable software versionsPostgreSQL: 9.4 - 11.4
External linkshttp://www.postgresql.org/about/news/1960/
Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
How the attacker can exploit this vulnerability?
The attacker would have to send a specially crafted request to the affected application in order to exploit this vulnerability.
The attacker would have to login to the system and perform certain actions in order to exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
4) Untrusted search path
EUVDB-ID: #VU20006
Risk: Low
CVSSv3.1: 3.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-10211
CWE-ID:
CWE-426 - Untrusted Search Path
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to EnterpriseDB Windows installer bundles an OpenSSL library that tries to load configuration from a hard-coded location on the system. This location usually does not exists, therefore an attacker can create a folder, place malicious configuration file in it and execute the configuration.
MitigationInstall updates from vendor's website.
