CVE-2008-7227
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedPartialBufferOutputStream2 in GeoServer before 1.6.1 and 1.7.0-beta1 attempts to flush buffer contents even when it is handling an "in memory buffer," which prevents the reporting of a service exception, with unknown impact and attack vectors.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidencePartialBufferOutputStream2 in GeoServer versions before 1.6.1 and 1.7.0-beta1 contains a logic flaw where it attempts to flush buffer contents even when handling an in-memory buffer. This prevents the proper reporting of service exceptions, creating a potential information disclosure or availability issue where error conditions go unreported.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify GeoServer versionCheck the GeoServer version by examining the geoserver.jar filename or the about/version page in the GeoServer admin console (usually at /geoserver/web/wicket/bookmarkable/org.geoserver.web.AboutPage)Affected if The installed version is 1.3.0, 1.3.2, 1.4.0, 1.5.0, 1.5.1, 1.5.2, 1.5.3, 1.6.0, 1.7.0, or 3.0, or any version before 1.6.1 or 1.7.0-beta1
-
Locate PartialBufferOutputStream2 classSearch the GeoServer application files (WEB-INF/lib directory) for partialbufferoutputstream2.jar or the class file PartialBufferOutputStream2.class within the geoserver jar filesAffected if The PartialBufferOutputStream2 class is present in the deployment
-
Check error response behaviorTrigger a service exception by making a request with intentionally malformed WMS/WFS parameters and observe if the error response is properly returnedAffected if Service exceptions are not being reported or returned to the client when using in-memory buffer handling
A user is affected if GeoServer version is 1.6.0 or earlier, or 1.7.0 or 3.0, and the PartialBufferOutputStream2 class is in use, causing service exceptions to go unreported.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade GeoServer to version 1.6.1 or later (or 1.7.0-beta1 or later) to resolve the buffer handling logic flaw in PartialBufferOutputStream2.
