wireshark - security update

Multiple vulnerabilities were discovered in the dissectors/parsers for
PKTC, IAX2, GSM CBCH and NCP which could result in denial of service.

This update also fixes many older less important issues by updating the
package to the version found in Debian 8 also known as Jessie.

For Debian 7 Wheezy, these problems have been fixed in version
1.12.1+g01b65bf-4+deb8u6~deb7u1.

We recommend that you upgrade your wireshark packages.
