The following updates has been released for Debian GNU/Linux:

Debian GNU/Linux 7 LTS:
DLA 1120-1: git security update

Debian GNU/Linux 8 and 9:
DSA 3989-1: dnsmasq security update

DLA 1120-1: git security update

Package : git
Version : 1:1.7.10.4-1+wheezy6
CVE ID : CVE-2017-14867
Debian Bug : 876854

joernchen discovered that the git-cvsserver subcommand of Git, a
distributed version control system, suffers from a shell command
injection vulnerability due to unsafe use of the Perl backtick
operator. The git-cvsserver subcommand is reachable from the
git-shell subcommand even if CVS support has not been configured
(however, the git-cvs package needs to be installed).

For Debian 7 "Wheezy", these problems have been fixed in version
1:1.7.10.4-1+wheezy6.

We recommend that you upgrade your git packages.
