This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.
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.
"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
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."
