Gentoo Linux Security Advisory 202409-32 - Multiple vulnerabilities have been discovered in nginx, the worst of which could result in denial of service. Versions greater than or equal to 1.26.2-r2 are affected.

### Impact Clients could clobber values set by intermediate proxies (such as X-Forwarded-For) by providing a underscore version of the same header (X-Forwarded_For). Any users trusting headers set by their proxy may be affected. Attackers may be able to downgrade connections to HTTP (non-SSL) or redirect responses, which could cause confidentiality leaks if combined with a separate MITM attack. ### Patches v6.4.3/v5.6.9 now discards any headers using underscores if the non-underscore version also exists. Effectively, allowing the proxy defined headers to always win. ### Workarounds Nginx has a [underscores_in_headers](https://nginx.org/en/docs/http/ngx_http_core_module.html#underscores_in_headers) configuration variable to discard these headers at the proxy level. Any users that are implicitly trusting the proxy defined headers for security or availability should immediately cease doing so until upgraded to the fixed versions.

Ubuntu Security Notice 7014-1 - It was discovered that the nginx ngx_http_mp4 module incorrectly handled certain malformed mp4 files. In environments where the mp4 directive is in use, a remote attacker could possibly use this issue to cause nginx to crash, resulting in a denial of service.

For modern applications built on Kubernetes and microservices, platform engineering is not just about building functional systems but also about embedding security into the fabric of those systems.

### Summary GeoNode is vulnerable to an XML External Entity (XXE) injection in the style upload functionality of GeoServer leading to Arbitrary File Read. ### Details GeoNode's GeoServer has the ability to upload new styles for datasets through the [`dataset_style_upload` view](https://github.com/GeoNode/geonode/blob/99b0557da5c7db23c72ad39e466b88fe43edf82d/geonode/geoserver/urls.py#L70-L72). ```py # https://github.dev/GeoNode/geonode/blob/99b0557da5c7db23c72ad39e466b88fe43edf82d/geonode/geoserver/views.py#L158-L159 @login_required def dataset_style_upload(request, layername): def respond(*args, **kw): kw['content_type'] = 'text/html' return json_response(*args, **kw) ... sld = request.FILES['sld'].read() # 1 sld_name = None try: # Check SLD is valid ... sld_name = extract_name_from_sld(gs_catalog, sld, sld_file=request.FILES['sld']) # 2 except Exception as e: respond(errors=f"The uploaded SLD file is not valid X...

Cybersecurity researchers have disclosed a security flaw impacting Microsoft Azure Kubernetes Services that, if successfully exploited, could allow an attacker to escalate their privileges and access credentials for services used by the cluster. "An attacker with command execution in a Pod running within an affected Azure Kubernetes Services cluster could download the configuration used to

Automad version 2.0.0-alpha.4 suffers from a persistent cross site scripting vulnerability.

### Impact In DSpace 7.0 through 7.6.1, when an HTML, XML or JavaScript Bitstream is downloaded, the user's browser _may_ execute any embedded JavaScript. If that embedded JavaScript is malicious, there is a risk of an XSS attack. This attack may only be initialized by a user who already has Submitter privileges in the repository. The submitter must upload the malicious HTML/XML/JavaScript file themselves. The attack itself would not occur until a different authenticated user downloads the malicious file. CORS and CSRF protection built into DSpace help to limit the impact of the attack (and may block it in some scenarios). If the repository is configured to only download HTML / XML / JavaScript Bitstreams using the [`Content-Disposition: attachment`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Disposition) header, then the attack is no longer possible. See "Workarounds" below. ### Patches The fix is included in both 8.0 and 7.6.2. Please upgrade to one of t...
