All supported architectures
A vulnerability in Asterisk could allow a remote attacker to cause
a Denial of Service condition.
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:
