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:
https://security-tracker.debian.org/tracker/zsh
