### Summary A denial of service vulnerability in JSON-Java was discovered by [ClusterFuzz](https://google.github.io/clusterfuzz/). A bug in the parser means that an input string of modest size can lead to indefinite amounts of memory being used. There are two issues: (1) the parser bug can be used to circumvent a check that is supposed to prevent the key in a JSON object from itself being another JSON object; (2) if a key does end up being a JSON object then it gets converted into a string, using `\` to escape special characters, including `\` itself. So by nesting JSON objects, with a key that is a JSON object that has a key that is a JSON object, and so on, we can get an exponential number of `\` characters in the escaped string. ### Severity High - Because this is an already-fixed DoS vulnerability, the only remaining impact possible is for existing binaries that have not been updated yet. ### Proof of Concept ```java package orgjsonbug; import org.json.JSONObject; /** * Illus...
A group of academics has disclosed a new "software fault attack" on AMD's Secure Encrypted Virtualization (SEV) technology that could be potentially exploited by threat actors to infiltrate encrypted virtual machines (VMs) and even perform privilege escalation. The attack has been codenamed CacheWarp (CVE-2023-20592) by researchers from the CISPA Helmholtz Center for Information Security. It

Netflix, Spotify, Twitter, PayPal, Slack. All down for millions of people. How a group of teen friends plunged into an underworld of cybercrime and broke the internet—then went to work for the FBI.
Government entities in the Middle East are the target of new phishing campaigns that are designed to deliver a new initial access downloader dubbed IronWind. The activity, detected between July and October 2023, has been attributed by Proofpoint to a threat actor it tracks under the name TA402, which is also known as Molerats, Gaza Cyber Gang, and shares tactical overlaps with a pro-Hamas
The Vietnamese threat actors behind the Ducktail stealer malware have been linked to a new campaign that ran between March and early October 2023, targeting marketing professionals in India with an aim to hijack Facebook business accounts. "An important feature that sets it apart is that, unlike previous campaigns, which relied on .NET applications, this one used Delphi as the programming
Ubuntu Security Notice 6465-3 - Yu Hao and Weiteng Chen discovered that the Bluetooth HCI UART driver in the Linux kernel contained a race condition, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service. Lin Ma discovered that the Netlink Transformation subsystem in the Linux kernel contained a null pointer dereference vulnerability in some situations. A local privileged attacker could use this to cause a denial of service.
The !CVE Project is an initiative to track and identify security issues that are not acknowledged by vendors but still are important for the security community.
