Package: integrit Version: 4.1-1.1+b1 Severity: normal Dear Maintainer,
I've had integrit crash several times with a segmentation fault: $ integrit -C /etc/integrit/integrit.conf -cu Segmentation fault dmesg has: integrit[17557]: segfault at 804e48c ip 0804e48c sp bfb32fbc error 14 Unfortunately, this seems to be tricky to reproduce reliably. It was crashing repeatedly each time I ran the command above. When I ran integrit under gdb, the crash didn't happen. When I apt-get installed valgrind to investigate further, the segfault stopped happening altogether (with no changes to integrit.conf or known.cdb or anything else as far as I can see). Sadly I don't have a coredump. (gdb) x/10i 0x804e48c 0x804e48c <__unified_syscall+33>: pop %ebp 0x804e48d <__unified_syscall+34>: pop %ebx 0x804e48e <__unified_syscall+35>: pop %esi 0x804e48f <__unified_syscall+36>: pop %edi 0x804e490 <__unified_syscall+37>: cmp $0xffffff7c,%eax 0x804e495 <__unified_syscall+42>: jb 0x804e4a4 <__unified_syscall+57> 0x804e497 <__unified_syscall+44>: neg %eax 0x804e499 <__unified_syscall+46>: push %eax 0x804e49a <__unified_syscall+47>: call 0x804eaa0 <__errno_location> 0x804e49f <__unified_syscall+52>: popl (%eax) Valgrind finds a valid problem with an uninitialized pointer being passed to munmap (munmap call is at cdb.c:56, problematic curr_cdb defined at missing.c:136 and then passed uninitialized to open_current_state_cdb). However this problem appears to be too late in the program to cause the segfault I'm seeing. Segfault seems to happen before config file is done parsing since nothing is yet printed to the terminal. I know this is likely not enough information to debug this. I'm reporting it here just in case someone else has a similar problem and has more relevant info.
