A vulnerability classified as critical has been found in PostgreSQL 8.0.23/8.1.11/8.3.8 (Database Software). This affects the function substring. The manipulation of the argument third with an unknown input leads to a numeric error vulnerability. CWE is classifying the issue as CWE-189. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The bitsubstr function in backend/utils/adt/varbit.c in PostgreSQL 8.0.23, 8.1.11, and 8.3.8 allows remote authenticated users to cause a denial of service (daemon crash) or have unspecified other impact via vectors involving a negative integer in the third argument, as demonstrated by a SELECT statement that contains a call to the substring function for a bit string, related to an "overflow."

The weakness was presented 02/02/2010 with Intevydis as Bug 559259 as not defined bug report (Bugzilla). It is possible to read the advisory at bugzilla.redhat.com.
