Dear Maintainer,
I've been using tripwire for several years now, and never had troubles
with it until this morning (perhaps [not] coincidentally with the
updated glibc6).
Now it segfaults a short time after starting. An strace of it comes
out something like this at the end:
openat(AT_FDCWD, "/etc/nsswitch.conf", O_RDONLY|O_CLOEXEC) = 3
fstat(3, {st_mode=S_IFREG|0644, st_size=545, ...}) = 0
read(3, "# /etc/nsswitch.conf\n#\n# Example"..., 4096) = 545
--- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0xe0} ---
write(2, "Software interrupt forced exit: "..., 51Software interrupt
forced exit: Segmentation Fault
) = 51
--- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x421} ---
+++ killed by SIGSEGV (core dumped) +++
I did this several times, and other files in /etc failed instead of
nsswitch.conf (passwd was one).
Since there's no dbgsym package for this version of tripwire, I
rebuilt from source (using gcc 10), and, after installing, it worked
fine with no segfault. However, this was version 2.4.3.7-3, not
2.4.3.7-3+b3: there doesn't seem to be a source for the "+b3" version.
I have coredumps and full strace if anyone needs it.
