CVE-ID: CVE-2014-8161

CWE-ID: CWE-209 - Information Exposure Through an Error Message

Exploit availability: No

Description

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

PostgreSQL before 9.0.19, 9.1.x before 9.1.15, 9.2.x before 9.2.10, 9.3.x before 9.3.6, and 9.4.x before 9.4.1 allows remote authenticated users to obtain sensitive column values by triggering constraint violation and then reading the error message.

Mitigation

Update the affected packages.
dev-db/postgresql to version: 9.4.3

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Code Injection

EUVDB-ID: #VU30420

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2015-0241

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to improper input validation in a (1) large number of digits when processing a numeric formatting template, which triggers a buffer over-read, or (2) crafted timestamp formatting template, which triggers a buffer overflow. A remote attacker can send a specially crafted request and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Update the affected packages.
dev-db/postgresql to version: 9.4.3

3) Stack-based buffer overflow

EUVDB-ID: #VU34851

Risk: High

CVE-ID: CVE-2015-0242

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing a floating point number with a large precision, as demonstrated by using the to_char function. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Update the affected packages.
dev-db/postgresql to version: 9.4.3

5) SQL injection

EUVDB-ID: #VU30422

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2015-0244

CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.

Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.

Mitigation

Update the affected packages.
