    Package : zsh
    CVE ID : CVE-2021-45444

    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 the oldstable distribution (buster), this problem has been fixed
    in version 5.7.1-1+deb10u1.

    For the stable distribution (bullseye), this problem has been fixed in
    version 5.8-6+deb11u1.

    We recommend that you upgrade your zsh packages.

    For the detailed security status of zsh please refer to
    its security tracker page at:
