Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Stack-based buffer overflow
EUVDB-ID: #VU18861
Risk: Medium
CVSSv3.1: 7 [CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-10164
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing users passwords. A remote authenticated user can change his/her password to a specially crafted string, trigger stack-based buffer overflow and execute arbitrary code on the target system or crash the PostgreSQL process.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationInstall updates from vendor's website.
Vulnerable software versionsPostgreSQL: 10.0 - 11.3

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote authenticated user via the local network (LAN).
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?

2) Buffer overflow
EUVDB-ID: #VU18862
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: N/A
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing a specifically crafted message during the SCRAM authentication process in a libpq-enabled client. A remote attacker can trick the victim to connect to a malicious PostgreSQL server, trigger memory corruption and execute arbitrary code on the target client system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system. MitigationInstall updates from vendor's website.
