3. Description:

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

A double-free flaw was found in the connection handling. An unauthenticated attacker could exploit this flaw to crash the PostgreSQL back end by disconnecting at approximately the same time as the authentication time out is triggered. (CVE-2015-3165)

It was discovered that PostgreSQL did not properly check the return values of certain standard library functions. If the system is in a state that would cause the standard library functions to fail, for example memory exhaustion, an authenticated user could exploit this flaw to disclose partial memory contents or cause the GSSAPI authentication to use an incorrect keytab file. (CVE-2015-3166)

It was discovered that the pgcrypto module could return different error messages when decrypting certain data with an incorrect key. This can help an authenticated user to launch a possible cryptographic attack, although no suitable attack is currently known. (CVE-2015-3167)

Red Hat would like to thank the PostgreSQL project for reporting these issues. Upstream acknowledges Benkocs Norbert Attila as the original reporter of CVE-2015-3165 and Noah Misch as the original reporter of CVE-2015-3166 and CVE-2015-3167.

All PostgreSQL users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. If the postgresql92-postgresql service is running, it will be automatically restarted after installing this update.
