Package: smcroute
Version: 0.95-1
Severity: important
Tags: patch
Dear Maintainer,
* What led up to the situation?
I use smcroute to route over vtun interfaces. After upgrade from
squeeze to wheezy, it segfaults when there are vtun interfaces active.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Patch smcroute to not deref a NULL-pointer. The first run, the
ifa->ifa_addr is NULL, but it seems to call the function twice, and the second
time the field is set, so in the end it works fine.
* What was the outcome of this action?
smcroute does not segfault anymore
* What outcome did you expect instead?
Please find attached a patch to fix a NULL-pointer dereference. The manpage for
struct ifaddr says explicitly that ifa_addr can be NULL, so that should be
checked.
