Public bug reported: SUMMARY
As a defense against machine code injection against buffer overflow bugs, most Linux distributions have worked over the years to remove as many rwx memory mappings as possible in processes. I checked this on several of my systems and unfortunately I found that many KDE processes do have rwx memory mappings. I chose to report this bug against the kded package because it is one of the most fundamental affected KDE process I found. However, the problem seems to be more general in KDE. I apologize in advance for not finding a better software package to report this problem. STEPS TO REPRODUCE 1. Log in Plasma 2. Run the following command: $ grep rwx /proc/$(pidof kded5)/maps OBSERVED RESULT $ grep rwx /proc/$(pidof kded5)/maps 7f68d7c2a000-7f68d7c3a000 rwxp 00000000 00:00 0 EXPECTED RESULT No output ProblemType: Bug DistroRelease: Ubuntu 19.04 Package: kded5 5.56.0-0ubuntu1 Uname: Linux 5.1.1-050101-generic x86_64 ApportVersion: 2.20.10-0ubuntu27 Architecture: amd64 CurrentDesktop: KDE Date: Tue May 14 08:41:00 2019 SourcePackage: kded UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: kded (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug disco ** Bug watch added: KDE Bug Tracking System #407496 https://bugs.kde.org/show_bug.cgi?id=407496 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1828936 Title: many KDE processes have rwx memory mappings To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kded/+bug/1828936/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
