Ubuntu Security Notice 6700-2 - It was discovered that the Layer 2 Tunneling Protocol implementation in the Linux kernel contained a race condition when releasing PPPoL2TP sockets in certain conditions, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the ext4 file system implementation in the Linux kernel did not properly handle block device modification while it is mounted. A privileged attacker could use this to cause a denial of service or possibly expose sensitive information.

Ubuntu Security Notice 6704-2 - It was discovered that the NVIDIA Tegra XUSB pad controller driver in the Linux kernel did not properly handle return values in certain error conditions. A local attacker could use this to cause a denial of service. Quentin Minster discovered that the KSMBD implementation in the Linux kernel did not properly handle session setup requests.

### Summary Symfony 1 has a gadget chain due to dangerous unserialize in `sfNamespacedParameterHolder` class that would enable an attacker to get remote code execution if a developer unserialize user input in his project. ### Details This vulnerability present no direct threat but is a vector that will enable remote code execution if a developper deserialize user untrusted data. For example: ```php public function executeIndex(sfWebRequest $request) { $a = unserialize($request->getParameter('user')); } ``` We will make the assumption this is the case in the rest of this explanation. Symfony 1 provides the class `sfNamespacedParameterHolder` which implements `Serializable` interface. In particular, when an instance of this class is deserialized, the normal php behavior is hooked by implementing `unserialize()` method: ```php public function unserialize($serialized) { $this->__unserialize(unserialize($serialized)); } ``` Which make an array access on the ...

### Summary _A file upload path traversal vulnerability has been identified in the application, enabling attackers to replace or create files with extensions like .json, .zip, .css, .gif, etc. This security flaw poses severe risks, that can allow attackers to inject arbitrary code on the server, undermine integrity of backup files by overwriting existing files or creating new ones, and exfiltrate sensitive data using CSS exfiltration techniques._ ### Installation Configuration - Grav CMS 1.10.44 - Apache web server - php-8.2 ### Details _**Vulnerable code location:**_ grav/system/src/Grav/Common/Media/Traits/MediaUploadTrait.php/checkFileMetadata() method_ public function checkFileMetadata(array $metadata, string $filename = null, array $settings = null): string { // Add the defaults to the settings. $settings = $this->getUploadSettings($settings); // Destination is always needed (but it can be set in defaults). $self = $settings['self'] ?? f...

A China-linked threat cluster leveraged security flaws in Connectwise ScreenConnect and F5 BIG-IP software to deliver custom malware capable of delivering additional backdoors on compromised Linux hosts as part of an "aggressive" campaign.
