Crash when converting deeply-nested or cyclical JS objects to BSON

    XMLWordPrintable

    Details

    • Type: Bug
    • Status: Closed
    • Priority: Major - P3
    • Resolution: Fixed
    • Affects Version/s: 2.4.6
    • Fix Version/s: 2.6.0-rc0
    • Component/s: JavaScript, MapReduce
    • Labels:
    • Environment:
      unix
    • Backwards Compatibility:
      Minor Change
    • Operating System:
      ALL
    • Steps To Reproduce:
      Hide

      1. Create collection, documents something like

      {
          _id: ObjectId("..."),
         data: {
             "some":"kind of",
             "trivial": "data"
         }
         document: DBRef("otherCollection", ObjectID("..."))
      }

      2. Insert a reasonable number of them:
      > db.audit.count()
      4002

      3. Simple query:

      db.audit.group({
          keyf:function(doc){ return {doc:doc.document} },
          cond: {},
          reduce: function(c, r){ r.audits.push(r) }, 
          initial: {audits: []}})

      4. Watch as mongod segfaults.
