Title:	Debian: Security Advisory (DLA-781-1)
Summary:	The remote host is missing an update for the Debian 'asterisk' package(s) announced via the DLA-781-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'asterisk' package(s) announced via the DLA-781-1 advisory. Vulnerability Insight: Two security vulnerabilities were discovered in Asterisk, an Open Source PBX and telephony toolkit. CVE-2014-2287 channels/chan_sip.c in Asterisk when chan_sip has a certain configuration, allows remote authenticated users to cause a denial of service (channel and file descriptor consumption) via an INVITE request with a (1) Session-Expires or (2) Min-SE header with a malformed or invalid value. CVE-2016-7551 The overlap dialing feature in chan_sip allows chan_sip to report to a device that the number that has been dialed is incomplete and more digits are required. If this functionality is used with a device that has performed username/password authentication RTP resources are leaked. This occurs because the code fails to release the old RTP resources before allocating new ones in this scenario. If all resources are used then RTP port exhaustion will occur and no RTP sessions are able to be set up. For Debian 7 Wheezy, these problems have been fixed in version 1:1.8.13.1~ dfsg1-3+deb7u5. We recommend that you upgrade your asterisk packages.

Solution: Please install the updated package(s). CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
