CVE-2007-2727 (GCVE-0-2007-2727)

Vulnerability from cvelistv5 – Published: 2007-05-16 22:00 – Updated: 2024-08-07 13:49
VLAI
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.
