Description

postgresql-8.3.8-1.fc11 has been submitted as an update for Fedora 11. http://admin.fedoraproject.org/updates/postgresql-8.3.8-1.fc11 postgresql-8.3.8-1.fc10 has been submitted as an update for Fedora 10. http://admin.fedoraproject.org/updates/postgresql-8.3.8-1.fc10 The Red Hat Security Response Team has rated this issue as having low security impact; a future update may address this flaw. The LOAD support in PostgreSQL changed in version 8.2 where non-superuser users can use LOAD to load modules in the plugins subdirectory (prior to 8.2 this feature was only available to superusers). As a result, if a plugin causes a crash in pre-8.2 versions, it was not considered a security hole since only the database administrator could cause the crash, not just any user. This also only causes a momentary denial of service during crash recovery. As well, Red Hat does not ship any plugins by default. postgresql-8.3.8-1.fc11 has been pushed to the Fedora 11 stable repository. If problems still persist, please make note of it in this bug report. postgresql-8.3.8-1.fc10 has been pushed to the Fedora 10 stable repository. If problems still persist, please make note of it in this bug report. MITRE's CVE-2009-3229 record: ----------------------------- The core server component in PostgreSQL 8.4 before 8.4.1, 8.3 before 8.3.8, and 8.2 before 8.2.14 allows remote authenticated users to cause a denial of service (backend shutdown) by "re-LOAD-ing" libraries from a certain plugins directory.
