Description
According to the version in its SIP banner, the version of Asterisk
running on the remote host is potentially affected by a vulnerability
that could allow a remote attacker to crash the server. This issue may
be exploited when the attacker has a valid SCCP (Skinny) ID and closes
a connection when in certain call states. A null pointer is left
behind and can cause the server to crash when the pointer is later
dereferenced.
Note the fix for AST-2012-008 was incomplete.
