A software update from cybersecurity company CrowdStrike appears to have inadvertently disrupted IT systems globally.

### Summary `BinaryHttpParser` does not properly validate input values thus giving attackers almost complete control over the HTTP requests constructed from the parsed output. Attackers can abuse several issues individually to perform various injection attacks including HTTP request smuggling, desync attacks, HTTP header injections, request queue poisoning, caching attacks and Server Side Request Forgery (SSRF). Attacker could also combine several issues to create well-formed messages for other text-based protocols which may result in attacks beyond the HTTP protocol. ### Details **Path, Authority, Scheme** The BinaryHttpParser class implements the readRequestHead method which performs most of the relevant parsing of the received request. The data structure prefixes values with a variable length integer value. The algorithm to create a variable length integer value is below: ``` def encode_int(n): if n < 64: base = 0x00 l = 1 elif n in range(64, 16384): ...

Three newly discovered SMTP smuggling attack techniques can exploit misconfigurations and design decisions made by at least 50 email-hosting providers.

### Summary An issue in the OpenSearch reporting plugin allows unintended access to private tenant resources like notebooks. The system did not properly check if the user was the resource author when accessing resources in a private tenant, leading to potential data being revealed. ### Impact The lack of proper access control validation for private tenant resources in the OpenSearch observability and reporting plugins can lead to unintended data access. If an authorized user with observability or reporting roles is aware of another user's private tenant resource ID, such as a notebook, they can potentially read, modify, or take ownership of that resource, despite not being the original author, thus impacting the confidentiality and integrity of private tenant resources. The impact is confined to private tenant resources, where authorized users may gain inappropriate visibility into data intended to be private from other users within the same OpenSearch instance, potentially violatin...

Ubuntu Security Notice 6901-1 - It was discovered that stunnel did not properly validate client certificates when configured to use both the redirect and verifyChain options. A remote attacker could potentially use this issue to obtain sensitive information by accessing the tunneled service.

Cybersecurity researchers have uncovered security shortcomings in SAP AI Core cloud-based platform for creating and deploying predictive artificial intelligence (AI) workflows that could be exploited to get hold of access tokens and customer data. The five vulnerabilities have been collectively dubbed SAPwned by cloud security firm Wiz. "The vulnerabilities we found could have allowed attackers

The group — which has targeted Israel, Saudi Arabia, and other nations — often uses spear-phishing and legitimate remote management tools but is developing a brand-new homegrown tool set.

The tactic is not new, but there has been a steady increase in its use as of this spring.

It was discovered that the ATA over Ethernet (AoE) driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the netfilter connection tracker for netlink in the Linux kernel did not properly perform reference counting in some error conditions. A local attacker could possibly use this to cause a denial of service (memory exhaustion). Various other issues were also addressed.
