I did some digging on this issue and found out, that these "buffer overflow detected" messages are triggered by -D_FORTIFY_SOURCE=3, which seems to be active since Ubuntu 24.04. This is why the problem wasn't noticed on Debian nor in 4.3.30-1build2 from the jammy, since both still use -D_FORTIFY_SOURCE=2.
As a workaround I created a little patch, that builds the package with -D_FORTIFY_SOURCE=2, that should work around the issue. Next step would be finding the root cause and avoid the buffer overflows. ** Patch added: "fortify2.patch" https://bugs.launchpad.net/ubuntu/+source/xymon/+bug/2078638/+attachment/5821577/+files/fortify2.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2078638 Title: coredumps with Xymon on 24.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xymon/+bug/2078638/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
