Technical Details:
The kernels used in Debian GNU/Linux 2.2 have been found to have multiple security problems. This is a list of problems based on the 2.2.19 release notes as found on http://www.linux.org.uk/ : * binfmt_misc used user pages directly * the CPIA driver had an off-by-one error in the buffer code which made it possible for users to write into kernel memory * the CPUID and MSR drivers had a problem in the module unloading code which could case a system crash if they were set to automatically load and unload (please note that Debian does not automatically unload kernel modules) * There was a possible hang in the classifier code * The getsockopt and setsockopt system calls did not handle sign bits correctly which made a local DoS and other attacks possible * The sysctl system call did not handle sign bits correctly which allowed a user to write in kernel memory * ptrace/exec races that could give a local user extra privileges * possible abuse of a boundary case in the sockfilter code * SYSV shared memory code could overwrite recently freed memory which might cause problems * The packet length checks in the masquerading code were a bit lax (probably not exploitable) * Some x86 assembly bugs caused the wrong number of bytes to be copied. * A local user could deadlock the kernel due to bugs in the UDP port allocation. All these problems are fixed in the 2.2.19 kernel, and it is highly recommend that you upgrade machines to this kernel. Please note that kernel upgrades are not done automatically. You will have to explicitly tell the packaging system to install the right kernel for your system.

Summary:

Frequently Asked Questions

No, you can scan concurrently as many assets as you want. Please note that you must be aware of the hardware requeriments of the platform to ensure a good performance.

No, you can add as many assest as you want. It doesn't matters if you have millions of assets, we won't charge you for that.

No. The software is completely free. We have no intention to charge you to use the software, in fact - it completely goes against our beliefs and business model.

A vulnerability is defined in the ISO 27002 standard as “A weakness of an asset or group of assets that can be exploited by one or more threats” (International Organization for Standardization, 2005)

We generate revenue by providing support and other services for customers that require a subscription so they get guaranteed support and enterprise services. To use Mageni's Platform is completely free, with no limits at all.

Yes. Mageni understands that there are professionals and businesses that need commercial support so Mageni provides an active support subscription with everything needed to run Mageni's Platform reliably and securely.

No, we don't store the information of your vulnerabilities in our servers.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
