another obvious bug in chkutmp.c
_Only if_ this is reproducible, can you redirect the output of
ps ax -o "tty,pid,ruser,args"
to a file and attach it?
[...]
The fetchps() function may need further proof-reading to avoid stack-smashing. Upstream has merged only some of the fixes in 0.49, without adding the missing fixes in a later release. UT_LINESIZE and UT_PIDSIZE have the same value, 12, but still the copy loop is wrong (patch attached). Unrelated to the crash, the copy loop for ps_args may need 0-termination.
Since there hasn't been any response here, the larger patch for this is attached to bug 626067. chkrootkit-0.49-2.fc13 has been submitted as an update for Fedora 13. https://admin.fedoraproject.org/updates/chkrootkit-0.49-2.fc13 chkrootkit-0.49-2.fc12 has been submitted as an update for Fedora 12. https://admin.fedoraproject.org/updates/chkrootkit-0.49-2.fc12 chkrootkit-0.49-2.fc14 has been submitted as an update for Fedora 14. https://admin.fedoraproject.org/updates/chkrootkit-0.49-2.fc14 chkrootkit-0.49-2.fc14 has been pushed to the Fedora 14 testing repository.
