chkproc reports " OooPS, not expected XXXXXX value"

[Lupe Christoph]

I run chkrootkit hourly with a customr output filter to intercept attacks. For a while now, I get these two lines that are not filtered out by my filter script:

 OooPS, not expected 105876 value
chkproc: Warning: Possible LKM Trojan installed

With varying PIDs.

While I would have my filter drop the first line, I will not drop the second. So I'm annoyed by hourly mails from this I have to check just to see it's that bug again.

For me, that just an annoyance. But there are probably people would be alarmed by this message.

This a know and fixed bug, see Debian Bug #982998. Please update the chkrootkit package to 0.55-2.

Thank you.
