Debian DLA-639-1 : mactelnet security update

critical Nessus Plugin ID 93692

Synopsis

The remote Debian host is missing a security update.

Description

CVE-2016-7115 Buffer overflow in the handle_packet function in mactelnet.c in the client in MAC-Telnet 0.4.3 and earlier allows remote TELNET servers to execute arbitrary code via a long string in an MT_CPTYPE_ENCRYPTIONKEY control packet.

For Debian 7 'Wheezy', these problems have been fixed in version 0.3.4-1+deb7u1.

We recommend that you upgrade your mactelnet packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected mactelnet-client, and mactelnet-server packages.
