Ubuntu Security Notice USN-6302-1
Ubuntu Security Notice 6302-1 - It was discovered that Vim incorrectly handled memory when opening certain files. If an attacker could trick a user into opening a specially crafted file, it could cause Vim to crash, or possibly execute arbitrary code. This issue only affected Ubuntu 22.04 LTS. It was discovered that Vim did not properly perform bounds checks in the diff mode in certain situations. An attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS and Ubuntu 22.04 LTS.

Dell VxRail versions earlier than 7.0.450, contain(s) an OS command injection vulnerability in VxRail Manager. A local authenticated attacker could potentially exploit this vulnerability, leading to the execution of arbitrary OS commands on the application's underlying OS, with the privileges of the vulnerable application. Exploitation may lead to a system take over by an attacker.

Dell VxRail, versions prior to 7.0.410, contain a Container Escape Vulnerability. A local high-privileged attacker could potentially exploit this vulnerability, leading to the execution of arbitrary OS commands on the container's underlying OS. Exploitation may lead to a system take over by an attacker.

Hello everyone! Great news for my open source Scanvus project! You can now perform vulnerability checks on Linux hosts and docker images not only using the Vulners.com API, but also with the Vulns.io VM API. It’s especially nice that all the code to support the new API was written and contributed by colleagues from Vulns.io. […]
