Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200703-14 (Asterisk: SIP Denial of Service)

 The MU Security Research Team discovered that Asterisk contains a NULL pointer dereferencing error in the SIP channel when handling request messages.
 Impact :

 A remote attacker could cause an Asterisk server listening for SIP messages to crash by sending a specially crafted SIP request message.
 Workaround :

 There is no known workaround at this time.

Solution
