Updated [Microsoft.Diagnostics.Tracing.TraceEvent](https://github.com/Microsoft/perfview) from 3.1.16 to 3.2.4. <details> <summary>Release notes</summary> _Sourced from [Microsoft.Diagnostics.Tracing.TraceEvent's releases](https://github.com/Microsoft/perfview/releases)._ ## 3.2.4 ## Security This release contains security hardening fixes for a number of malformed-input parsing and path-traversal vulnerabilities: - Bounds-checking for malformed event payloads in the BPerf ULZ777 decompressor and event-record parser - Bounds-checking for malformed metadata in the GCDynamic, RegisteredTraceEventParser (TDH), Dynamic, and EventPipe V3 parsers - Bounds-checking for malformed PE CodeView and Resource directory entries - Path containment hardening for PDB extraction (zipped ETL + container PDBs), DiagSession resource extraction, R2R perf map writes, PdbScope module paths, and dynamic manifest writes - Path-traversal and command-execution hardening for Source Server lookups ## What's Changed * Update CsWin32 Package Version by @brianrob in microsoft/perfview#2425 * Fix incorrect field offsets when parsing ETW events with fixed-count array fields by @Copilot in microsoft/perfview#2427 * Retarget Native Profiler Builds To VS 2026 V145 Toolset by @brianrob in microsoft/perfview#2428 * Stabilize XamlMessageBox UI-thread dispatch test by @brianrob in microsoft/perfview#2430 **Full Changelog**: microsoft/perfview@v3.2.3...v3.2.4 ## 3.2.3 ## What's Changed * Upgrade Microsoft.Windows.CsWin32 to 0.3.209 (GHSA-ghhp-997w-qr28) by @Copilot in microsoft/perfview#2409 * Enable Spectre mitigations and linker optimizations for EtwClrProfiler by @danmoseley in microsoft/perfview#2410 * Fix 'unhanded' / 'occured' typos in UnhandledExceptionDialog body text by @SAY-5 in microsoft/perfview#2413 * Fix GCStats failures on dotnet trace gc-verbose collections (#2414) by @cincuranet in microsoft/perfview#2415 * C entrypoint fixes by @zachcmadsen in microsoft/perfview#2421 ## New Contributors * @SAY-5 made their first contribution in microsoft/perfview#2413 **Full Changelog**: microsoft/perfview@v3.2.2...v3.2.3 ## 3.2.2 ## What's Changed * Fix PDB Symbol Resolution for Unmerged Windows Traces by @brianrob in microsoft/perfview#2407 **Full Changelog**: microsoft/perfview@v3.2.1...v3.2.2 ## 3.2.1 ## Native and R2R Symbol Download and Parsing Now Available As of this release, if you capture a trace using [`dotnet-trace collect-linux`](https://learn.microsoft.com/en-us/dotnet/core/diagnostics/dotnet-trace#dotnet-trace-collect-linux) or [`record-trace`](https://github.com/microsoft/one-collect/tree/main/record-trace), **native and R2R symbols can now be downloaded and resolved at analysis time**. All .NET symbols (both native and R2R) are available on the Microsoft Symbol Server. Additionally, many Azure Linux symbol files are available on the Microsoft Symbol Server. For those targeting other distros, PerfView and TraceEvent are capable of pulling those symbol files from local directories by adding a local symbol path pointing to the files. Most of the work for this was completed in PerfView and TraceEvent 3.2.1 with the final required fixes present in this release. ## What's Changed * Optimize nettrace-to-TraceLog Conversion by @brianrob in microsoft/perfview#2403 * Embed missing System.Text.Json transitive dependencies in PerfView by @brianrob in microsoft/perfview#2404 **Full Changelog**: microsoft/perfview@v3.2.0...v3.2.1 ##
