Technical Details:
Several vulnerabilities have been discovered in asterisk, an Open Source PBX and telephony toolkit. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2009-0041 It is possible to determine valid login names via probing, due to the IAX2 response from asterisk (AST-2009-001). CVE-2008-3903 It is possible to determine a valid SIP username, when Digest authentication and authalwaysreject are enabled (AST-2009-003). CVE-2009-3727 It is possible to determine a valid SIP username via multiple crafted REGISTER messages (AST-2009-008). CVE-2008-7220 CVE-2007-2383 It was discovered that asterisk contains an obsolete copy of the Prototype JavaScript framework, which is vulnerable to several security issues. This copy is unused and now removed from asterisk (AST-2009-009). CVE-2009-4055 It was discovered that it is possible to perform a denial of service attack via RTP comfort noise payload with a long data length (AST-2009-010). For the stable distribution (lenny), these problems have been fixed in version 1:1.4.21.2~dfsg-3+lenny1. The security support for asterisk in the oldstable distribution (etch) has been discontinued before the end of the regular Etch security maintenance life cycle. You are strongly encouraged to upgrade to stable. For the testing distribution (squeeze) and the unstable distribution (sid), these problems have been fixed in version 1:1.6.2.0~rc7-1. We recommend that you upgrade your asterisk Linux Distribution Packages.

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".
