Asterisk is an open source telephony engine and toolkit.

A vulnerability has been found in Asterisk's handling of certain encrypted streams where the res_srtp module has been loaded but video support has not been enabled.

A remote attacker could send a specially crafted SDP message to the Asterisk daemon, possibly resulting in a Denial of Service condition.

There is no known workaround at this time.

All Asterisk users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/asterisk-1.8.8.2"
