Debian LTS: Security Advisory for zsh (DLA-2470-1)

The remote host is missing an update for the 'zsh' package(s) announced via the DLA-2470-1 advisory.

Several security vulnerabilities were found and corrected in zsh, a powerful shell and scripting language. Off-by-one errors, wrong parsing of shebang lines and buffer overflows may lead to unexpected behavior. A local, unprivileged user can create a specially crafted message file or directory path. If the receiving user is privileged or traverses the aforementioned path, this leads to privilege escalation.

'zsh' package(s) on Debian Linux.

Checks if a vulnerable package version is present on the target host.

For Debian 9 stretch, these problems have been fixed in version 5.3.1-4+deb9u4. We recommend that you upgrade your zsh packages.
