Background ========== PostgreSQL is an open source database based on the POSTGRES database management system. It includes several contributed scripts including the make_oidjoins_check script. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-db/postgresql <= 7.4.5-r1 >= 7.4.5-r2 *>= 7.3.7-r2 Description =========== The make_oidjoins_check script insecurely creates temporary files in world-writeable directories with predictable names. Impact ====== A local attacker could create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem. When make_oidjoins_check is called, this would result in file overwrite with the rights of the user running the utility, which could be the root user. Workaround ========== There is no known workaround at this time. Resolution ========== All PostgreSQL users should upgrade to the latest version: # emerge sync # emerge -pv ">=dev-db/postgresql-7.4.5-r2" # emerge ">=dev-db/postgresql-7.4.5-r2" Upgrade notes: PostgreSQL 7.3.x users should upgrade to the latest available 7.3.x version to retain database compatibility. References ========== [ 1 ] Trustix Advisory #2004-0050 http://www.trustix.org/errata/2004/0050/ Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200410-16.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
