It was discovered that zsh, a powerful shell and scripting language, did not prevent recursive prompt expansion. This would allow an attacker to execute arbitrary commands into a user’s shell, for instance by tricking a vcs_info user into checking out a git branch with a specially crafted name.
For Debian 8 jessie, these problems have been fixed in version 5.0.7-5+deb8u4.
We recommend that you upgrade your zsh packages.
