"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.

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."
