Original description
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.
Affected software
- PHP < 5.3.14≥ 5.4.0 < 5.4.4 Fixed in: 5.3.14, 5.4.4 exact match
