Ubuntu Security Notice 6819-4 - Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel did not properly validate H2C PDU data, leading to a null pointer dereference vulnerability. A remote attacker could use this to cause a denial of service. Chenyuan Yang discovered that the RDS Protocol implementation in the Linux kernel contained an out-of-bounds read vulnerability. An attacker could use this to possibly cause a denial of service.

Debian Linux Security Advisory 5718-1 - It was discovered that Org Mode for Emacs is prone to arbitrary shell code evaluation when opening a specially crafted Org file.

Threat actors with suspected ties to China and North Korea have been linked to ransomware and data encryption attacks targeting government and critical infrastructure sectors across the world between 2021 and 2023. While one cluster of activity has been associated with the ChamelGang (aka CamoFei), the second cluster overlaps with activity previously attributed to Chinese and North Korean

The heightened regulatory and legal pressure on software-producing organizations to secure their supply chains and ensure the integrity of their software should come as no surprise. In the last several years, the software supply chain has become an increasingly attractive target for attackers who see opportunities to force-multiply their attacks by orders of magnitude. For example, look no

Debian Linux Security Advisory 5715-2 - The update for composer released as DSA 5715 introduced a regression in the handling of git feature branches. Updated composer packages are now available to address this issue.

### 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...

Threat actors are exploiting a novel attack technique in the wild that leverages specially crafted management saved console (MSC) files to gain full code execution using Microsoft Management Console (MMC) and evade security defenses. Elastic Security Labs has codenamed the approach GrimResource after identifying an artifact ("sccm-updater.msc") that was uploaded to the VirusTotal malware

### Impact The content of a document included using `{{include reference="targetdocument"/}}` is executed with the right of the includer and not with the right of its author. This means that any user able to modify the target document can impersonate the author of the content which used the `include` macro. ### Patches This has been patched in XWiki 15.0 RC1 by making the default behavior safe. ### Workarounds Make sure to protect any included document to make sure only allowed users can modify it. A workaround have been provided in 14.10.2 to allow forcing to execute the included content with the target content author instead of the default behavior. See https://extensions.xwiki.org/xwiki/bin/view/Extension/Include%20Macro#HAuthor for more details. ### References https://jira.xwiki.org/browse/XWIKI-5027 https://jira.xwiki.org/browse/XWIKI-20471 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki.org](https://j...

Change Healthcare has detailed the types of medical and patient data that was stolen in a recent ransomware attack.

## Summary ZIP files uploaded to the server-side endpoint handling a `CodeChecker store` are not properly sanitized. An attacker can exercise a path traversal to make the `CodeChecker server` load and display files from an arbitrary location on the server machine. ## Details ### Target The vulnerable endpoint is `/<PRODUCT_URL>/v6.53/CodeCheckerService@massStoreRun`. ### Exploit overview The attack is made possible by improper sanitization at one point in the process. 1. When the ZIP file is uploaded by `CodeChecker store`, it is first unzipped to a temporary directory (safely). 2. When deciding which files to insert into CodeChecker's internal database, the decision is made based on the `content_hashes.json` in the ZIP. An attacker has control over the contents of this file. 3. After reading that file, the paths specified in the JSON are normalized by this code: https://github.com/Ericsson/codechecker/blob/fa41e4e5d9566b5a4f5a80a27bddec73a5146f5a/web/server/codechecker_server/a...
