Package: procps
Version: 2:3.3.17-5
Severity: serious

Dear maintainer,

calling kill(1) with negative PIDs always delivers the signal to the
current process group, instead of the one with the specified PID. That
is because the binary always calls kill(2) with 0 as first argument.

This is known and has been fixed upstream:
https://gitlab.com/procps-ng/procps/-/issues/211
https://gitlab.com/procps-ng/procps/-/commit/79097e55e4b08ec8c1de8332e32cf03c4be1d4ec

This bug affects both Debian stable (Bullseye) and testing/unstable.

Best,
Felix
