Synopsis
Multiple vulnerabilities in Asterisk might allow remote attackers to cause
a Denial of Service condition, or conduct other attacks.
2.
Impact Information
Background
Asterisk is an open source telephony engine and toolkit.
Description
Multiple vulnerabilities have been reported in Asterisk:
- Nick Baggott reported that Asterisk does not properly process
overly long ASCII strings in various packets (CVE-2009-2726).
- Noam Rathaus and Blake Cornell reported a flaw in the IAX2 protocol
implementation (CVE-2009-2346).
- amorsen reported an input
processing error in the RTP protocol implementation
(CVE-2009-4055).

disclosure flaw related to the REGISTER message (CVE-2009-3727).
- A vulnerability was found in the bundled Prototype JavaScript
library, related to AJAX calls (CVE-2008-7220).
Impact
A remote attacker could exploit these vulnerabilities by sending a
specially crafted package, possibly causing a Denial of Service
condition, or resulting in information disclosure.
