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.
