Debian Security Advisory DSA 1896-1 (opensaml, shibboleth-sp)

Published: 2009-10-06 00:49:40
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:


Technical Details:
Several vulnerabilities have been discovered in the opensaml and shibboleth-sp Linux Distribution Packages, as used by Shibboleth 1.x: Chris Ries discovered that decoding a crafted URL leads to a crash (and potentially, arbitrary code execution). Ian Young discovered that embedded NUL characters in certificate names were not correctly handled, exposing configurations using PKIX trust validation to impersonation attacks. Incorrect processing of SAML metadata ignored key usage constraints. For the old stable distribution (etch), these problems have been fixed in version 1.3f.dfsg1-2+etch1 of the shibboleth-sp Linux Distribution Packages, and version 1.1a-2+etch1 of the opensaml Linux Distribution Packages. For the stable distribution (lenny), these problems have been fixed in version 1.3.1.dfsg1-3+lenny1 of the shibboleth-sp Linux Distribution Packages, and version 1.1.1-2+lenny1 of the opensaml Linux Distribution Packages. The unstable distribution (sid) does not contain Shibboleth 1.x Linux Distribution Packages. This update requires restarting the affected services (mainly Apache) to become effective. We recommend that you upgrade your Shibboleth 1.x Linux Distribution Packages.

The remote host is missing an update to opensaml, shibboleth-sp announced via advisory DSA 1896-1.

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".
