Technical Details:
Paul Starzetz and Wojciech Purczynski of isec.pl discovered a critical security vulnerability in the memory management code of Linux inside the mremap(2) system call. Due to missing function return value check of internal functions a local attacker can gain root privileges. For the stable distribution (woody) this problem has been fixed in version 2.4.18-14.2 of kernel-source, version 2.4.18-14 of alpha images, version 2.4.18-12.2 of i386 images, version 2.4.18-5woody7 of i386bf images and version 2.4.18-1woody4 of powerpc images. Other architectures will probably mentioned in a separate advisory or are not affected (m68k). For the unstable distribution (sid) this problem is fixed in version 2.4.24-3 for source, i386 and alpha images and version 2.4.22-10 for powerpc images. This problem is also fixed in the upstream version of Linux 2.4.25 and 2.6.3. We recommend that you upgrade your Linux kernel Linux Distribution Packages immediately.

Summary:
The remote host is missing an update to kernel-source-2.4.18, kernel-image-2.4.18-1-alpha, kernel-image-2.4.18-1-i386, kernel-image-2.4.18-i386bf, kernel-patch-2.4.18-powerpc announced via advisory DSA 438-1.

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".
