Hi,
yes, we are both talking about the clients running as root.
dnsmasq is compiled with gcc, so CCpp should catch the crash.
I compiled dnsmasq from source and tested this binary (which also
crashes due to the same bug). These crashes are overlooked also.
ProcessUnpackaged ist set to yes.
Even killall -ABRT dnsmasq manages to escape ABRT.
I updated abrt* from updates-testing, no changes.
Starting to sound like a bug, then. Maybe file it against the ccpp plugin?
Hi,
this is not really a bug. AFAIK dnsmasq drops privileges and thus calls
setuid(). Applications doing this are not dumped by default because of
security reasons - kernel does not even call the coredump hook. You can
enable this by setting the value of /proc/sys/fs/suid_dumpable to either
1 or 2. See man 5 proc for details.
