Scientific Linux Security Update : postgresql on SL5.x i386/x86_64

Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

PostgreSQL is an advanced object-relational database management system
(DBMS).

A flaw was found in the way the crypt() password hashing function from
the optional PostgreSQL pgcrypto contrib module performed password
transformation when used with the DES algorithm. If the password
string to be hashed contained the 0x80 byte value, the remainder of
the string was ignored when calculating the hash, significantly
reducing the password strength. This made brute-force guessing more
efficient as the whole password was not required to gain access to
protected resources. (CVE-2012-2143)

Note: With this update, the rest of the string is properly included in
the DES hash
therefore, any previously stored password values that
are affected by this issue will no longer match. In such cases, it
will be necessary for those stored password hashes to be updated.

All PostgreSQL users are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. If the
postgresql service is running, it will be automatically restarted
after installing this update.
