Description:
A vulnerability has been reported in Asterisk, which can be exploited by malicious people to bypass certain security restrictions.
The vulnerability is caused due to Asterisk not properly enforcing ACLs when handling SIP INVITES. This can be exploited to e.g. perform calls, although the caller's network is forbidden via the "deny" and "permit" options in sip.conf.
The vulnerability is reported in all Asterisk Open Source 1.6.1 versions prior to 1.6.1.8.
