Background ========= PostgreSQL is a SQL compliant, open source object-relational database management system. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-db/postgresql < 8.0.2-r1 *> = 7.4.7-r2 *> = 8.0.1-r3 > = 8.0.2-r1 Description ========== PostgreSQL gives public EXECUTE access to a number of character conversion routines, but doesn't validate the given arguments (CAN-2005-1409). It has also been reported that the contrib/tsearch2 module of PostgreSQL misdeclares the return value of some functions as "internal" (CAN-2005-1410). Impact ===== An attacker could call the character conversion routines with specially setup arguments to crash the backend process of PostgreSQL or to potentially gain administrator rights. A malicious user could also call the misdeclared functions of the contrib/tsearch2 module, resulting in a Denial of Serviceor other, yet uninvestigated, impacts. Workaround ========= There is no known workaround at this time. Resolution ========= All PostgreSQL users should update to the latest available version and follow the guide at # emerge --sync # emerge --ask --oneshot --verbose dev-db/postgresql References ========= [ 1 ] CAN-2005-1409 https://www.cve.org/CVERecord?id=CVE-2005-1409 [ 2 ] CAN-2005-1410 https://www.cve.org/CVERecord?id=CVE-2005-1410 [ 3 ] PostgreSQL Announcement Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200505-12 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.
