  概要

Asterisk is prone to multiple buffer-overflow vulnerabilities because it fails to perform adequate boundary checks on user-supplied data before copying it to insufficiently sized buffers. Exploiting these issues may allow an attacker to corrupt memory and cause denial-of-service conditions or potentially execute arbitrary code in the context of the application. These issues affect the following versions: Asterisk Open Source prior to 1.4.18.1 and 1.4.19-rc3. Asterisk Open Source prior to 1.6.0-beta6 Asterisk Business Edition prior to C.1.6.1 AsteriskNOW prior to 1.0.2 Asterisk Appliance Developer Kit prior to Asterisk 1.4 revision 109386 s800i (Asterisk Appliance) prior to 1.1.0.2
