Amazon Linux AMI update for postgresql92

1) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU41879

Risk: Medium

CVSSv3.1: 5.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2014-0067

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

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The "make check" command for the test suites in PostgreSQL 9.3.3 and earlier does not properly invoke initdb to specify the authentication requirements for a database cluster to be used for the tests, which allows local users to gain privileges by leveraging access to this cluster.

Mitigation

Update the affected packages:

3) 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.

EUVDB-ID: #VU34851

Risk: High

CVSSv3.1: 8.1 [AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:U/RC:C]

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.
