Google observed some undocumented (to the best of their knowledge) behavior of the indirect branch predictors, specifically relative to _ret_ instructions. The research they conducted appears to show that this behavior does not seem to create exploitable security vulnerabilities in the software they have tested. They would like to better understand the impact and implications for different software stacks, thus they welcome feedback or further research. Included is proof of concept code.

This is a path traversal vulnerability that impacts the CreateIndexHandler and DeleteIndexHandler found within Bleve search library. These vulnerabilities enable the attacker to delete any directory owned by the user recursively, and create a new directory in any location which the server has write permissions to. This is Google's proof of concept exploit.

libresolv's DNS packet handler suffered from heap out-of-bounds write to infinite-loop denial of service vulnerabilities. This is a proof of concept exploit from Google.

Log4j 2.15.0 was released to address the widely reported JNDI Remote Code Execution (RCE) (CVE-2021-44228) vulnerability in Log4j. Shortly thereafter, 2.16.0 was released to address a Denial of Service (DoS) vulnerability (CVE-2021-45046). When examining the 2.15.0 release, Google security engineers found several issues with the Log4j 2.15.0 patch that showed that the severity of the issue addressed in 2.16 was in fact worse than initially understood. This is Google's proof of concept exploit.

### Summary If a user is granted the `admin:users` scope, they may escalate their own privileges by making themselves a full admin user. ### Details The `admin:users` scope allows a user to edit user records: > admin:users > > Read, write, create and delete users and their authentication state, not including their servers or tokens. > > -- https://jupyterhub.readthedocs.io/en/stable/rbac/scopes.html#available-scopes However, this includes making users admins. Admin users are granted scopes beyond `admin:users` making this a mechanism by which granted scopes may be escalated. ### Impact The impact is relatively small in that `admin:users` is already an extremely privileged scope only granted to trusted users. In effect, `admin:users` is equivalent to `admin=True`, which is not intended. Note that the change here only prevents escalation to the built-in JupyterHub admin role that has unrestricted permissions. It does not prevent users with e.g. `groups` permissions from granting ...

Windows Firewall Control version 6.11.0 suffers from an unquoted service path vulnerability.

As AI technologies continue to advance at a rapid pace, privacy, security and governance teams can't expect to achieve strong AI governance while working in isolation.

Cybersecurity researchers have discovered a new "0.0.0.0 Day" impacting all major web browsers that malicious websites could take advantage of to breach local networks. The critical vulnerability "exposes a fundamental flaw in how browsers handle network requests, potentially granting malicious actors access to sensitive services running on local devices," Oligo Security researcher Avi Lumelsky

View CSAF 1. EXECUTIVE SUMMARY CVSS v4 6.9 ATTENTION: Exploitable remotely/low attack complexity Vendor: Dorsett Controls Equipment: InfoScan Vulnerabilities: Exposure of Sensitive Information To An Unauthorized Actor, Path Traversal 2. RISK EVALUATION Successful exploitation of these vulnerabilities could allow an attacker to expose sensitive information, resulting in data theft and misuse of credentials. 3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS The following Dorsett Controls products are affected: InfoScan: v1.32, v1.33, and v1.35 3.2 Vulnerability Overview 3.2.1 EXPOSURE OF SENSITIVE INFORMATION TO AN UNAUTHORIZED ACTOR CWE-200 Dorsett Controls InfoScan is vulnerable due to a leak of possible sensitive information through the response headers and the rendered JavaScript prior to user login. CVE-2024-42493 has been assigned to this vulnerability. A CVSS v3.1 base score of 5.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N). A CVSS v4 score has a...

Researchers at Aqua Security discovered the "Shadow Resource" attack vector and the "Bucket Monopoly" problem, where threat actors can guess the name of S3 buckets based on their public account IDs.
