Debian: DSA-5892-1 critical: atop data sanitization issue

It was discovered that Atop, a monitor tool for system resources and
process activity, always tried to connect to the port of atopgpud
(an additional daemon gathering GPU statistics not shipped in Debian)
while performing insufficient sanitising of the data read from this
port.

With this update, additional validation is added and by default atop
no longer tries to connect to the atopgpud daemon port unless explicitly
enabled via -k.

For the stable distribution (bookworm), this problem has been fixed in
version 2.8.1-1+deb12u1.

We recommend that you upgrade your atop packages.

For the detailed security status of atop please refer to
