"Joern Schneeweisz discovered that git, a distributed revision control
system, did not correctly handle maliciously constructed ssh:// URLs.
This allowed an attacker to run an arbitrary shell command, for
instance via git submodules.

For Debian 7 'Wheezy', these problems have been fixed in version
1:1.7.10.4-1+wheezy5.

We recommend that you upgrade your git packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
