CVE-2017-12424 Open this link in a new tabHow to fix?
Upgrade Debian:11 shadow to version 1:4.5-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream shadow package and not the shadow package as distributed by Debian.
See How to fix? for Debian:11 relevant fixed versions and status.
In shadow before 4.5, the newusers tool could be made to manipulate internal data structures in ways unintended by the authors. Malformed input may lead to crashes (with a buffer overflow or other memory corruption) or other unspecified behaviors. This crosses a privilege boundary in, for example, certain web-hosting environments in which a Control Panel allows an unprivileged user account to create subaccounts.
