Debian Security Advisory DSA 1581-1 (gnutls13)

CVSS Base Vector:


Technical Details:
Several remote vulnerabilities have been discovered in GNUTLS, an implementation of the SSL/TLS protocol suite. NOTE: The libgnutls13 Linux Distribution Package, which provides the GNUTLS library, does not contain logic to automatically restart potentially affected services. You must restart affected services manually (mainly Exim, using /etc/init.d/exim4 restart) after applying the update, to make the changes fully effective. Alternatively, you can reboot the system. The following vulnerabilities have been identified: A pre-authentication heap overflow involving oversized session resumption data may lead to arbitrary code execution (CVE-2008-1948). Repeated client hellos may result in a pre-authentication denial of service condition due to a null pointer dereference (CVE-2008-1949). Decoding cipher padding with an invalid record length may cause GNUTLS to read memory beyond the end of the received record, leading to a pre-authentication denial of service condition (CVE-2008-1950). For the stable distribution (etch), these problems have been fixed in version 1.4.4-3+etch1. (Builds for the arm architecture are currently not available and will be released later.) For the unstable distribution (sid), these problems will be fixed soon. We recommend that you upgrade your GNUTLS Linux Distribution Packages.

The remote host is missing an update to gnutls13 announced via advisory DSA 1581-1.

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".
