keycloak-services: keycloak-services: Delegated admin escalates to realm-admin via group move

A flaw was found in the group-move and organization group reparenting endpoints of the keycloak-services component. This component is responsible for core authentication and authorization services in the Red Hat build of Keycloak. The issue occurs because the system fails to check if a target parent group confers administrative roles when a group is moved. A delegated administrator can exploit this to move a group they control under an administrative group, causing all…

Red Hat Enterprise Linux (crun, xfsprogs, glib-networking): Mehrere Schwachstellen

A flaw was found in the xfs_admin utility in xfsprogs. The tool does not properly validate user-supplied parameters, allowing operating system command injection. A local attacker can exploit this issue by providing crafted input arguments, which may result in arbitrary command execution and local privilege escalation depending on how xfs_admin is executed.

Red Hat Enterprise Linux: Mehrere Schwachstellen

A flaw was found in Cockpit. A local authenticated user with control over a target account's home directory can exploit a privileged symlink dereference vulnerability in the `ssh-add-public-key.sh` helper. When this helper runs with elevated privileges, it can be tricked into following attacker-controlled symlinks within the `.ssh` or `authorized_keys` paths. This allows the attacker to arbitrarily change file ownership and modes, potentially leading to local privilege…

Red Hat Enterprise Linux: Mehrere Schwachstellen

A flaw was found in Cockpit. This vulnerability allows a remote attacker, without prior authentication, to send specially crafted fragmented WebSocket messages. These messages accumulate without a total-size limit, leading to unbounded memory exhaustion and a denial of service in the `cockpit-ws` service.

activestorage: Active Storage: Remote code execution via unsafe file extension handling in media processing

Active Storage makes it simple to upload and reference files in cloud services and attach those files to Active Record objects. Prior to 8.1.4.1 and 8.0.5.2, ActiveStorage::Blob#open writes a blob to a tempfile whose name carries the extension of the uploaded filename, and hands that path to ffprobe (VideoAnalyzer, AudioAnalyzer), ffmpeg (VideoPreviewer) and ImageMagick (ImageAnalyzer, the :mini_magick variant processor). These tools select a decoder from the file extension…

activestorage: Active Storage: File size validation bypass via missing direct-upload content length constraints

### Impact `ActiveStorage::Service::GCSService#url_for_direct_upload` does not bind the declared content length into the signed direct-upload URL, and `#headers_for_direct_upload` returns no length constraint, so the URL authorizes an upload body of any size. A direct-upload client could store a file larger than the `byte_size` it declared, and the resulting blob keeps the declared size, possibly bypassing application file size validations and quotas. This is the weakness…

actionpack: actionpack: IP address spoofing via crafted Forwarded header

Action Pack is a framework for handling and responding to web requests. From 8.1 until 8.1.4.1, Since Rails 8.1.0, ActionDispatch::RemoteIp derives request.remote_ip from Rack::Request#forwarded_for, which under Rack 3 reads the RFC 7239 Forwarded header in preference to X-Forwarded-For. When a reverse proxy appends the client address to X-Forwarded-For but passes a client-supplied Forwarded header through unchanged, request.remote_ip returns an address chosen by the client…

activesupport: Active Support: Denial of Service via unescaped regular expressions in safe_constantize

### Impact When constant lookup raises `LoadError`, `ActiveSupport::Inflector#safe_constantize` (and `String#safe_constantize`) builds a regular expression from the requested constant name without escaping it, so a caller that passes untrusted input lets the attacker choose the source of a pattern that the application compiles. Crafted patterns can trigger defects in Ruby's regular expression compiler, possibly leading to a crash of the server process, and repeated requests…

actionpack: actionpack: Session retention across logout via race condition in CacheStore

### Impact `ActionDispatch::Session::CacheStore` writes a session back to the cache at the end of each request that loaded it, without checking that the session's cache entry still exists. When a concurrent request destroys the session, through `reset_session` on logout or by deleting its cache entry on the server, a request that loaded the session earlier and finishes later restores it under its original session ID. Logout and server-side revocation could therefore fail to…

activesupport: Active Support: Cross-site scripting via MessagePack deserialization

### Impact `ActiveSupport::MessagePack` serializes an `ActiveSupport::SafeBuffer` as its bytes alone and deserializes it as a new `SafeBuffer`, so a buffer that is no longer `html_safe?` (for example, one mutated in place with `gsub!`) is restored as `html_safe`. If such a buffer holds untrusted input and is stored through a MessagePack serializer, rendering it after it is loaded bypasses ERB auto-escaping, possibly leading to XSS. Applications on Rails 8.1 are affected if…

activestorage: activestorage: Denial of Service via filenames containing null bytes

Active Storage makes it simple to upload and reference files in cloud services and attach those files to Active Record objects. Prior to 8.1.4.1 and 8.0.5.2, ActiveStorage::Filename#base and #extension_with_delimiter, and therefore #extension, pass the stored filename unmodified to File.basename and File.extname, which raise ArgumentError when the name contains a NUL byte. Active Storage stores the client-supplied filename verbatim, so a user who is permitted to upload an…

actionpack: Action Pack: Web cache poisoning via improper Vary header generation during content negotiation

### Impact Action Pack negotiates the format of a rendered response from the `Accept`, `X-Requested-With` and, for XHR requests without `Accept`, `Content-Type` request headers, but `ActionController::Rendering#_set_vary_header` adds `Vary: Accept` only when the request carries a usable `Accept` header and the response has no `Vary` header yet. A response to a request without `Accept`, or to an XHR request, therefore omits the headers that selected its representation, and a…

activestorage: Active Storage: Denial of Service via thread exhaustion from streaming storage errors

Active Storage makes it simple to upload and reference files in cloud services and attach those files to Active Record objects. From 8.0 until 8.0.5.2 and 8.1.4.1, when Active Storage serves a file through its proxy controllers, ActiveStorage::Streaming#send_blob_stream handles an error from the storage service by calling head to send a 404 or 500 response. If the error occurs after the first chunk has been written, the response is already committed, and head replaces the…

actionmailbox: Action Mailbox: Inbound email forgery via Mailgun webhook signature replay

### Impact The Action Mailbox Mailgun ingress authenticates a request with an HMAC of the `timestamp` and `token` parameters concatenated without a separator, and `ActionMailbox::Ingresses::Mailgun::InboundEmailsController::Authenticator#recent?` rejects only timestamps more than 2 minutes in the past. Because the signature does not fix the boundary between the two values, a captured signed request can be presented with a timestamp far in the future, which the ingress then…

actionpack: Action Pack: Cross-Site Request Forgery via missing SameSite attribute on session cookies

### Impact Action Pack session stores other than `ActionDispatch::Session::CookieStore` (`CacheStore`, `MemCacheStore`, and third-party stores built on `AbstractStore`, `AbstractSecureStore` or the session mixins) write the session cookie without a `SameSite` attribute, regardless of `config.action_dispatch.cookies_same_site_protection`, which defaults to `:lax`. Only `CookieStore` applies the configured policy. In browsers that do not treat a cookie without the attribute as…

fast-xml-parser: fast-xml-parser: Denial of Service via quadratic rescanning of unterminated tags

### Summary With the non-default stopNodes option, a stop node's body with many " " anywhere after makes readStopNodeData() rescan the entire remaining input from every " ` exists - `OrderedObjParser.js:812-818` — on failure, `i` isn't advanced, so the next ` ` lookahead is neither cached nor bounded — `n` copies of ` ` means `n` scans over the remaining input, O(n²) work, before it finally throws. **Fix** 1. Throw immediately in `readStopNodeData()` when `readTagExp()`…

Nokogiri: Possible Use-After-Free when setting an attribute value via `Nokogiri::XML::Node#[]=` or `#lang=`

### Summary Nokogiri's CRuby native extension could leave a Ruby wrapper pointing to freed memory when replacing the value of an existing XML attribute via `Nokogiri::XML::Node#[]=` or `Nokogiri::XML::Node#lang=`. If Ruby code had already accessed the attribute's child nodes, replacing the value could free those native child nodes while their wrappers remained reachable. Using one of those child nodes afterwards could cause an invalid read and a possible segfault. This is…

Nokogiri : Possible SSRF on JRuby when resolving external DTDs or entities with `NONET` set

### Summary On JRuby, the `NONET` parse option did not block an external DTD or entity whose system identifier used a short-form IPv4 host, such as `http://127.1/` or `http://169.254.43518/`, or was an absolute path such as `/x.dtd` in a document parsed from a network URL. An application that parses untrusted XML with `DTDLOAD`, `DTDVALID` or `NOENT` could be made to send network requests, potentially enabling SSRF. Nokogiri 1.19.5 applies the `XML::Schema` check from…

python-pulpcore: pulpcore: Header content guard jq filter exposes the content-app environment

An **expression language injection** has been found in the HeaderContentGuard.permit function in publication.py of the content guard in the **Pulpcore** package. The guard is supposed to check a value in a request header. It saves a jq filter and runs that filter against the header when a client asks for content. The filter is not limited to the header, and jq's env builtin also returns the environment of the content process. A low-privileged network attacker or user who can…
