This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability. An information disclosure vulnerability exists in .NET 5.0, .NET Core 3.1 and .NET Core 2.1 when dumps created by the tool to collect crash dumps and dumps on demand are created with global read permissions on Linux and macOS. ### Patches * If you're using .NET 5.0, you should download and install Runtime 5.0.9 or SDK 5.0.206 (for Visual Studio 2019 v16.8) or SDK 5.0.303 (for Visual Studio 2019 V16.10) from https://dotnet.microsoft.com/download/dotnet-core/5.0. * If you're using .NET Core 3.1, you should download and install Runtime 3.1.18 or SDK 3.1.118 (for Visual Studio 2019 v16.4) or 3.1.412 (for Visual Studio 2019 v16.7 or later) from https://dotnet.microsoft.com/download/dotnet-core/3.1. * If you're using .NET Core 2.1, ...

### Impact _What kind of vulnerability is it? Who is impacted?_ In Hardened JavaScript, programs can `harden` objects to safely share objects with co-tenant programs without risk of these other programs tampering with their API surface. Hardening does not guarantee that objects are pure or immutable, so a hardened `Map`, for example is superficially tamper-proof, but any party holding a reference to the object can both read and write its contents. Based on this precedent, and because `TypedArray` instances cannot be frozen with `Object.isFrozen`, `harden` does not `freeze` `TypedArrays` and instead makes them non-extensible and makes all non-indexed properties non-writable and non-configurable. This is consistent with the treatment of `Map` because the indexed properties represent mutable content and non-indexed properties represent the API. Due to a defect in `harden`, properties that have names that parse as numbers but are not the same as the canonical representation of those numb...

### Impact Using jadx-gui to open a special zip file with entry containing HTML sequence like `<html><frame>` will cause interface to get stuck and throw exceptions like: ``` java.lang.RuntimeException: Can't build aframeset, BranchElement(frameset) 1,3 :no ROWS or COLS defined. at java.desktop/javax.swing.text.html.HTMLEditorKit$HTMLFactory.create(HTMLEditorKit.java:1387) at java.desktop/javax.swing.plaf.basic.BasicHTML$BasicHTMLViewFactory.create(BasicHTML.java:379) at java.desktop/javax.swing.text.CompositeView.loadChildren(CompositeView.java:112) ``` ### References https://www.oracle.com/java/technologies/javase/seccodeguide.html Guideline 3-7 / INJECT-7: Disable HTML display in Swing components: Many Swing pluggable look-and-feels interpret text in certain components starting with <html> as HTML. If the text is from an untrusted source, an adversary may craft the HTML such that other components appear to be present or to perform inclusion attacks. To disable the HTML render...

Missing Authentication for Critical Function in GitHub repository ikus060/rdiffweb prior to 2.5.0.

Reactor Netty HTTP Server, in versions 1.0.11 - 1.0.23, may request log headers in some cases of invalid HTTP requests. The logged headers may reveal valid access tokens to those with access to server logs. This may affect only invalid HTTP requests where logging at WARN level is enabled.

Shinken Solutions Shinken Monitoring Version 2.4.3 affected is vulnerable to Incorrect Access Control. The `SafeUnpickler` class found in `shinken/safepickle.py` implements a weak authentication scheme when unserializing objects passed from monitoring nodes to the Shinken monitoring server.

### Impact For some Post/Put Concourse endpoint containing `:team_name` in the URL, a Concourse user can send a request with body including `:team_name=team2` to bypass team scope check to gain access to certain resources belong to any other team. The user only needs a valid user session and belongs to team2. Exploitable endpoints: ``` {Path: "/api/v1/teams/:team_name/pipelines/:pipeline_name/jobs/:job_name/builds/:build_name", Method: "POST", Name: RerunJobBuild}, {Path: "/api/v1/teams/:team_name/pipelines/:pipeline_name/jobs/:job_name/pause", Method: "PUT", Name: PauseJob}, {Path: "/api/v1/teams/:team_name/pipelines/:pipeline_name/jobs/:job_name/unpause", Method: "PUT", Name: UnpauseJob}, {Path: "/api/v1/teams/:team_name/pipelines/:pipeline_name/jobs/:job_name/schedule", Method: "PUT", Name: ScheduleJob}, {Path: "/api/v1/teams/:team_name/pipelines/:pipeline_name/pause", Method: "PUT", Name: PausePipeline}, {Path: "/api/v1/teams/:team_name/pipelines/:pipeline_name/unpause", Method: ...
