How to fix?

Upgrade Debian:unstable asterisk to version 1:1.6.2.6-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream asterisk package and not the asterisk package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

The design of the dialplan functionality in Asterisk Open Source 1.2.x, 1.4.x, and 1.6.x; and Asterisk Business Edition B.x.x and C.x.x, when using the ${EXTEN} channel variable and wildcard pattern matches, allows context-dependent attackers to inject strings into the dialplan using metacharacters that are injected when the variable is expanded, as demonstrated using the Dial application to process a crafted SIP INVITE message that adds an unintended outgoing channel leg. NOTE: it could be argued that this is not a vulnerability in Asterisk, but a class of vulnerabilities that can occur in any program that uses this feature without the associated filtering functionality that is already available.
