Synopsis: Moderate: postgresql security update Issue Date: 2011-10-17 CVE Numbers: CVE-2011-2483 PostgreSQL is an advanced object-relational database management system (DBMS). A signedness issue was found in the way the crypt() function in the PostgreSQL pgcrypto module handled 8-bit characters in passwords when using Blowfish hashing. Up to three characters immediately preceding a non-ASCII character (one with the high bit set) had no effect on the hash result, thus shortening the effective password length. This made brute-force guessing more efficient as several different passwords were hashed to the same value. (CVE-2011-2483) Note: Due to the CVE-2011-2483 fix, after installing this update some users may not be able to log in to applications that store user passwords, hashed with Blowfish using the PostgreSQL crypt() function, in a back-end PostgreSQL database. Unsafe processing can be re-enabled for specific passwords (allowing affected users to log in) by changing their hash prefix to "$2x$". For Scientific Linux 6, the updated postgresql packages upgrade PostgreSQL to version 8.4.9. Refer to the PostgreSQL Release Notes for a full list of changes: http://www.postgresql.org/docs/8.4/static/release.html For Scientific Linux 4 and 5, the updated postgresql packages contain a backported patch. All PostgreSQL users are advised to upgrade to these updated packages, which correct this issue. If the postgresql service is running, it will be automatically restarted after installing this update.
