Description

This security bulletin contains information about 1 security vulnerability.

1) Cryptographic issues (CVE-ID: CVE-2012-2143)

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

The crypt_des (aka DES-based crypt) function in FreeBSD before 9.0-RELEASE-p2, as used in PHP, PostgreSQL, and other products, does not process the complete cleartext password if this password contains a 0x80 character, which makes it easier for context-dependent attackers to obtain access via an authentication attempt with an initial substring of the intended password, as demonstrated by a Unicode password. As per: http://git.php.net/?p=php-src.git;a=commitdiff;h=aab49e934de1fff046e659cbec46e3d053b41c34 and http://git.php.net/?p=php-src.git;a=commitdiff_plain;h=aab49e934de1fff046e659cbec46e3d053b41c34 PHP 5.3.13 and earlier are vulnerable.
