*** 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. lsb_release -rd Description: Ubuntu 20.04.4 LTS Release: 20.04 uname -a Linux ryzen7 5.4.0-107-lowlatency #121-Ubuntu SMP PREEMPT Thu Mar 24 16:45:08 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux pnscan 1.12+git20180612-2 ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: pnscan 1.12+git20180612-2 ProcVersionSignature: Ubuntu 5.4.0-107.121-lowlatency 5.4.174 Uname: Linux 5.4.0-107-lowlatency x86_64 ApportVersion: 2.20.11-0ubuntu27.23 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: KDE Date: Tue Apr 12 20:48:45 2022 InstallationDate: Installed on 2012-12-03 (3417 days ago) InstallationMedia: Kubuntu 12.10 "Quantal Quetzal" - Release amd64 (20121017.1) ProcEnviron: PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: pnscan UpgradeStatus: Upgraded to focal on 2020-04-29 (713 days ago) ** Affects: pnscan (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug focal -- Clamscan reports Unix.Tool.Pnscan-8031486-0 in 1.12+git20180612-2 pnscan version https://bugs.launchpad.net/bugs/1968806 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
