Package        : git
CVE ID         : CVE-2015-7545

Blake Burkhart discovered that the Git git-remote-ext helper incorrectly
handled recursive clones of git repositories. A remote attacker could
possibly use this issue to execute arbitary code by injecting commands
via crafted URLs.

For the oldstable distribution (wheezy), this problem has been fixed
in version 1:1.7.10.4-1+wheezy2.

For the stable distribution (jessie), this problem has been fixed in
version 1:2.1.4-2.1+deb8u1.

For the testing distribution (stretch), this problem has been fixed
in version 1:2.6.1-1.

For the unstable distribution (sid), this problem has been fixed in
version 1:2.6.1-1.

We recommend that you upgrade your git packages.
