SB2016121103 - Cryptographic issues in phpMyAdmin

Description

This security bulletin contains information about 1 security vulnerability.

1) Cryptographic issues (CVE-ID: CVE-2016-9847)

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

An issue was discovered in phpMyAdmin. When the user does not specify a blowfish_secret key for encrypting cookies, phpMyAdmin generates one at runtime. A vulnerability was reported where the way this value is created uses a weak algorithm. This could allow an attacker to determine the user's blowfish_secret and potentially decrypt their cookies. All 4.6.x versions (prior to 4.6.5), 4.4.x versions (prior to 4.4.15.9), and 4.0.x versions (prior to 4.0.10.18) are affected.

Remediation

Install update from vendor's website.
