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.

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 packages.
