Vulnerability CVE-2007-2727 - CERT Civis.Net

Vulnerability Name:

CVE-2007-2727 (CCN-34521)

Assigned:

2007-05-10

Published:

2007-05-10

Updated:

2022-11-07

Summary:

The mcrypt_create_iv function in ext/mcrypt/mcrypt.c in PHP before 4.4.7, 5.2.1, and possibly 5.0.x and other PHP 5 versions, calls php_rand_r with an uninitialized seed variable and therefore always generates the same initialization vector (IV), which might allow context-dependent attackers to decrypt certain data more easily because of the guessable encryption keys.
