CVE-2011-1315
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 · uneditedMemory leak in the messaging engine in IBM WebSphere Application Server (WAS) before 7.0.0.15 allows remote attackers to cause a denial of service (memory consumption) via network connections associated with a NULL return value from a synchronous JMS receive call.
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 confidenceMemory leak in IBM WebSphere Application Server messaging engine versions before 7.0.0.15. When a synchronous JMS receive call returns a NULL value, memory is not properly released, causing gradual memory consumption that can lead to denial of service when exploited via repeated network connections.

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 WebSphere Application Server versionRun the versionInfo.sh script (or versionInfo.bat on Windows) from the WebSphere bin directory, or check the install_root/properties/version directory for version filesAffected if The installed version is 7.0.0.13 or earlier, or matches one of the affected fix pack versions (2.0, 3.0, 3.0.2, 3.0.2.1, 3.0.2.2, 3.0.2.3, 3.0.2.4, 3.0.21, 3.5, 3.5.1, 3.5.2)
-
Confirm messaging engine is in useCheck for configured JMS resources in the WebSphere administrative console or by reviewing resources.xml configuration files in the config directoryAffected if JMS message-driven beans or JMS queues/topics are configured and the WebSphere version is vulnerable
-
Verify WebSphere edition and full version numberReview the installation directory for the installed.properties file or use the administrative console to view the full version string including the fix pack levelAffected if The full version shows a build level below 7.0.0.15
The environment is affected if WebSphere Application Server version is 7.0.0.13 or earlier, or one of the specific affected fix pack versions, AND the messaging engine with JMS functionality is configured and actively handling requests.
