+# Apache Hive — CWE-407 Scan Result: CLEAN
+
+**Date:** 2026-03-30
+**Scanner:** agent blackops
+**Scope:** ql/src/java/org/apache/hadoop/hive/ql/ (optimizer, parse, exec, metadata, plan)
+         standalone-metastore/metastore-server/
+
+## Summary
+
+Apache Hive is clean of CWE-407 algorithmic complexity defects. The codebase
+consistently uses HashSet for visited tracking, membership tests, and dedup
+operations throughout the query optimizer, parser, compiler, and metastore.
+
+## Key observations
+
+- `OperatorGraph.Cluster.members`: HashSet<Operator<?>>
+- `TezCompiler.unionOps`: HashSet<Operator<?>>
+- `TezCompiler.connect()` (Tarjan SCC): uses `nodes` Set for stack membership
+- `ColumnPrunerProcFactory`: HashSet for colNames membership
+- `PipelineTranslation.viewTransforms`: HashSet<String>
+- `SharedCache.*DeletedDuringPrewarm`: HashSet<String>
+- `SessionHiveMetaStoreClient.partitionVals`: HashSet<List<String>> for partition dedup
+- `Hive.createdDeltaDirs`: HashSet<Path> for ACID delta dir dedup
+- `GreedyPipelineFuser`: acknowledged O(N²) in sibling grouping but this is inherent compatibility checking
+
+Minor findings (no defect):
+- `SemanticAnalyzer.leftAliases/rightAliases`: ArrayList with .contains(), but N is join alias count (2-3)
+- `WindowingSpec.fillInWindowSpec.visited`: ArrayList with .contains(), but N is window spec chain depth (2-3)
+- `QueryPlanTreeTransformation.childrenOfDemux`: List with .contains(), but N is demux children (2-3)
+- `HiveRelDecorrelator.newLocalOutputs`: ArrayList with .contains(), but per-input column offsets (small)
+
+No data-proportional linear scans inside loops found.

+# LibreOffice CWE-407: OutlineView selected paragraphs O(P*S) linear scan
+#
+# In sd/source/ui/view/outlview.cxx, two methods scan maSelectedParas
+# (a vector) via std::find() inside a while-loop over all paragraphs:
+#
+# 1. BeginMovingHdl (line 1003): for each page-paragraph, std::find in
+#    maSelectedParas to determine selection state — O(P*S)
+# 2. SetSelectedPages (line 1476): same pattern — O(P*S)
+#
+# Where P = total paragraphs, S = selected paragraphs.
+#
+# Fix: build an unordered_set from maSelectedParas before the loop
+# for O(1) membership test.
+#
+# Severity: MEDIUM — Impress presentations with hundreds of slides
+# trigger this during slide reordering and selection operations.
+# At P=500, S=100: 50,000 comparisons reduced to 500.
