The Marvin Attack is a new side-channel attack on cryptographic implementations of RSA in which the attacker decrypts previously captured ciphertext by measuring, over a network, server response times to specially crafted messages. The attacker also may forge signatures with the same key as the one used for decryption. Red Hat published the principles and technical background of the Marvin Attack in September of 2023.Since that time, we have identified lots of other vulnerable implementations and have shipped fixes. Note that most of the CVEs in applications that use OpenSSL have only received

Cybersecurity researchers have disclosed details of a now-patched security flaw in Phoenix SecureCore UEFI firmware that affects multiple families of Intel Core desktop and mobile processors. Tracked as CVE-2024-0762 (CVSS score: 7.5), the "UEFIcanhazbufferoverflow" vulnerability has been described as a case of a buffer overflow stemming from the use of an unsafe variable in the Trusted Platform

The FTC has referred a complaint against TikTok and its parent company ByteDance to the Department of Justice.

### Impact A [cross-site scripting (XSS)](https://owasp.org/www-community/attacks/xss/) vulnerability was discovered in TinyMCE’s content extraction code. When using the `noneditable_regexp` option, specially crafted HTML attributes containing malicious code were able to be executed when content was extracted from the editor. ### Patches This vulnerability has been patched in TinyMCE 7.2.0, TinyMCE 6.8.4 and TinyMCE 5.11.0 LTS by ensuring that, when using the `noneditable_regexp` option, any content within an attribute is properly verified to match the configured regular expression before being added. ### Fix To avoid this vulnerability: * Upgrade to TinyMCE 7.2.0 or higher. * Upgrade to TinyMCE 6.8.4 or higher for TinyMCE 6.x. * Upgrade to TinyMCE 5.11.0 LTS or higher for TinyMCE 5.x (only available as part of commercial [long-term support](https://www.tiny.cloud/long-term-support/) contract). ### References * [TinyMCE 6.8.4](https://www.tiny.cloud/docs/tinymce/6/6.8.4-release-not...

### Impact A [cross-site scripting (XSS)](https://owasp.org/www-community/attacks/xss/) vulnerability was discovered in TinyMCE’s content parsing code. This allowed specially crafted noscript elements containing malicious code to be executed when that content was loaded into the editor. ### Patches This vulnerability has been patched in TinyMCE 7.2.0, TinyMCE 6.8.4 and TinyMCE 5.11.0 LTS by ensuring that content within noscript elements are properly parsed. ### Fix To avoid this vulnerability: * Upgrade to TinyMCE 7.2.0 or higher. * Upgrade to TinyMCE 6.8.4 or higher for TinyMCE 6.x. * Upgrade to TinyMCE 5.11.0 LTS or higher for TinyMCE 5.x (only available as part of commercial [long-term support](https://www.tiny.cloud/long-term-support/) contract). ### Acknowledgements Tiny thanks [Malav Khatri](https://malavkhatri.com/) and another reporter for their help identifying this vulnerability. ### References * [TinyMCE 6.8.4](https://www.tiny.cloud/docs/tinymce/6/6.8.4-release-notes/#...

Ubuntu Security Notice 6840-1 - Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, bypass security restrictions, cross-site tracing, or execute arbitrary code. Luan Herrera discovered that Thunderbird did not properly validate the X-Frame-Options header inside sandboxed iframe. An attacker could potentially exploit this issue to bypass sandbox restrictions to open a new window.

Ubuntu Security Notice 6818-4 - 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. It was discovered that the Intel Data Streaming and Intel Analytics Accelerator drivers in the Linux kernel allowed direct access to the devices for unprivileged users and virtual machines. A local attacker could use this to cause a denial of service.

Forcing Microsoft to compete fairly is the most important next step in building a better defense against foreign actors.

Ubuntu Security Notice 6835-1 - It was discovered that Ghostscript did not properly restrict eexec seeds to those specified by the Type 1 Font Format standard when SAFER mode is used. An attacker could use this issue to bypass SAFER restrictions and cause unspecified impact. This issue only affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 23.10. Thomas Rinsma discovered that Ghostscript did not prevent changes to uniprint device argument strings after SAFER is activated, resulting in a format-string vulnerability. An attacker could possibly use this to execute arbitrary code.
