Ubuntu Security Notice 7025-1 - It was discovered that LibreOffice would incorrectly handle digital signature verification after repairing a corrupted document. A remote attacker could possibly use this issue to forge valid signatures.

The first patch lets threat actors with low-level credentials still exploit the vulnerability, while the second fully resolves the flaw.

Many GitHub users this week received a novel phishing email warning of critical security holes in their code. Those who clicked the link for details were asked to distinguish themselves from bots by pressing a combination of keyboard keys that causes Microsoft Windows to download password-stealing malware. While it's unlikely that many programmers fell for this scam, it's notable because less targeted versions of it are likely to be far more successful against the average Windows user.

A misconfiguration flaw was found in Keycloak. This issue can allow an attacker to redirect users to an arbitrary URL if a 'Valid Redirect URI' is set to http://localhost or http://127.0.0.1, enabling sensitive information such as authorization codes to be exposed to the attacker, potentially leading to session hijacking.

There exists a use after free vulnerability in Reverb. Reverb supports the VARIANT datatype, which is supposed to represent an arbitrary object in C++. When a tensor proto of type VARIANT is unpacked, memory is first allocated to store the entire tensor, and a ctor is called on each instance. Afterwards, Reverb copies the content in tensor_content to the previously mentioned pre-allocated memory, which results in the bytes in tensor_content overwriting the vtable pointers of all the objects which were previously allocated. Reverb exposes 2 relevant gRPC endpoints: InsertStream and SampleStream. The attacker can insert this stream into the server’s database, then when the client next calls SampleStream they will unpack the tensor into RAM, and when any method on that object is called (including its destructor) the attacker gains control of the Program Counter. We recommend upgrading past git commit  https://github.com/google-deepmind/reverb/commit/6a0dcf4c9e842b7f999912f792aaa6f6bd261a2...

A flaw exists in the SAML signature validation method within the Keycloak XMLSignatureUtil class. The method incorrectly determines whether a SAML signature is for the full document or only for specific assertions based on the position of the signature in the XML document, rather than the Reference element used to specify the signed element. This flaw allows attackers to create crafted responses that can bypass the validation, potentially leading to privilege escalation or impersonation attacks.

This year, Congress only allocated $55 million in federal grant dollars to states for security and other election improvements.

A hacker claims Dell suffered a “minor” breach, exposing over 10,000 employee records. The incident raises cybersecurity concerns…

Until just a couple of years ago, only a handful of IAM pros knew what service accounts are. In the last years, these silent Non-Human-Identities (NHI) accounts have become one of the most targeted and compromised attack surfaces. Assessments report that compromised service accounts play a key role in lateral movement in over 70% of ransomware attacks. However, there’s an alarming disproportion

Hi, Rspack|Webpack developer team! ## Summary We discovered a DOM Clobbering vulnerability in Webpack’s AutoPublicPathRuntimeModule. The DOM Clobbering gadget in the module can lead to cross-site scripting (XSS) in web pages where scriptless attacker-controlled HTML elements (e.g., an img tag with an unsanitized name attribute) are present. We found the real-world exploitation of this gadget in the Canvas LMS which allows XSS attack happens through an javascript code compiled by Webpack (the vulnerable part is from Webpack). We believe this is a severe issue. If Webpack’s code is not resilient to DOM Clobbering attacks, it could lead to significant security vulnerabilities in any web application using Webpack-compiled code. ## Details ### Backgrounds DOM Clobbering is a type of code-reuse attack where the attacker first embeds a piece of non-script, seemingly benign HTML markups in the webpage (e.g. through a post or comment) and leverages the gadgets (pieces of js code) living in t...
