Vulnerability description

The vulnerability allows a remote user to perform service disruption.

PostgreSQL before 8.3.7, 8.2.13, 8.1.17, 8.0.21, and 7.4.25 allows remote authenticated users to cause a denial of service (stack consumption and crash) by triggering a failure in the conversion of a localized error message to a client-specified encoding, as demonstrated using mismatched encoding conversion requests. Per: https://bugzilla.redhat.com/show_bug.cgi?id=488156 "PostgreSQL allows remote authenticated users to cause a momentary denial of service (crash due to stack consumption) when there is a failure to convert a localized error message to the client-specified encoding. In releases 8.3.6, 8.2.12, 8.1.16. 8.0.20, and 7.4.24, a trivial misconfiguration is sufficient to provoke a crash. In older releases it is necessary to select a locale and client encoding for which specific messages fail to translate, and so a given installation may or may not be vulnerable depending on the administrator-determined locale setting. Releases 8.3.7, 8.2.13, 8.1.17, 8.0.21, and 7.4.25 are secure against all known variants of this issue."
