Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the git packages.

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.
