Package: aptitude
Version: 0.4.11.11-1+b1
Justification: user security hole
Severity: grave
Tags: security
Hi.
I'm running several intrusion detection systems, e.g. rkhunter (which
in turn uses unhide). For quite some time now, unhide gave me false
positives (I'm quite sure, that my system is not compromised), saying
that hidden processes were found.
After some trying, it seems that these processes come from aptitude
(e.g. when it's doing some operation, like starting up or so), though
I'm not absolutely sure.
As this makes IDS nearly useless, at least for all the times when
aptitude was running, I marked this bug grave/security,.... but please
feel free to degrade this ;)
rkhunter just uses unhide to scan for hidden processes, so I
concentrate on this.
Hidden processes are at least found, when using it in the "unhide sys"
mode,... not sure about "unhide proc",... and "unhide brute" always
segfaults for me.
The output is about the following:
Warning: Hidden processes found: 29662
29675
29686
29694
29704
29715
29721
29746
29752
30778
30811
31883
31895
31908
31921
621
629
712
756
779
786
But it's even possible that there are less processes found,.. but so
far it was mostly in that range (1- about 20 processes)
Is it possible that this comes from aptitude?
I've also CC'ed the unhide maintainer,.. perhaps he can give some adivce.
Thanks,
Chris.
