"The PostgreSQL Global Development Group reports :

Today the PHP, OpenBSD and FreeBSD communities announced updates to
patch a security hole involving their crypt() hashing algorithms. This
issue is described in CVE-2012-2143. This vulnerability also affects a
minority of PostgreSQL users, and will be fixed in an update release
on June 4, 2012.

Affected users are those who use the crypt(text, text) function with
DES encryption in the optional pg_crypto module. Passwords affected
are those that contain characters that cannot be represented with
7-bit ASCII. If a password contains a character that has the most
significant bit set (0x80), and DES encryption is used, that character
and all characters after it will be ignored."
