Title:	CentOS Update for postgresql CESA-2011:1377 centos5 i386
Summary:	The remote host is missing an update for the 'postgresql'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'postgresql' package(s) announced via the referenced advisory. Vulnerability Insight: 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 Red Hat Enterprise Linux 6, the updated postgresql packages upgrade PostgreSQL to version 8.4.9. Refer to the linked PostgreSQL Release Notes for a full list of changes. For Red Hat Enterprise 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. Affected Software/OS: postgresql on CentOS 5 Solution: Please install the updated packages.
