Red Hat: 2012:1036-01: postgresql: Moderate Advisory
Summary
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.
Upstream acknowledges Rubin Xu and Joseph Bonneau as the original reportersof this issue.
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.
