*** This bug is a security vulnerability ***
You have been subscribed to a public security bug by Seth Arnold (seth-arnold):
My system showed unusually high memory and swap usage for a few weeks,
also occasional lags in situations when it was always brisk before. I
naturally ran clamscan to check. Pnscan was flagged as containing the
malware. I removed and purged pnscan, and continued to scan for
anything else out of line. Saw nothing else, and rebooted. Memory and
swap usage was normal for several hours. Then I reinstalled pnscan from
the repository. Clamscan reported Unix.Tool.Pnscan-8031486-0 in pnscan
again. So I removed and purged pnscan again.
I recognize that clamscan could be misleading here, but I never saw this
report before, and it's clear that my memory and swap issues haven't
returned.
I'm going to suggest this is a security vulnerability, even though the
clamscan result might be misleading.
