--- Begin Message ---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. -- System Information: Debian Release: 7.0 APT prefers stable APT policy: (500, 'stable') Architecture: i386 (x86_64) Kernel: Linux 3.2.0-4-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=UTF-8 (charmap=locale: Cannot set LC_CTYPE to default locale: No such file or directory locale: Cannot set LC_ALL to default locale: No such file or directory ANSI_X3.4-1968) Shell: /bin/sh linked to /bin/bash Versions of packages smcroute depends on: ii libc6 2.13-38 smcroute recommends no packages. smcroute suggests no packages. -- Configuration Files: /etc/smcroute/startup.sh changed [not included] -- debconf information excluded--- ifvc.orig.c 2013-05-11 12:07:49.000000000 +0200 +++ ifvc.c 2013-05-11 12:06:51.000000000 +0200 @@ -50,7 +50,8 @@ } for (ifa = ifaddr; ifa != NULL; ifa = ifa->ifa_next) { - int family = ifa->ifa_addr->sa_family; + int family = 0; + if(ifa->ifa_addr) family = ifa->ifa_addr->sa_family; /* Skip non-IPv4 and non-IPv6 interfaces */ if ((family != AF_INET) && (family != AF_INET6)) continue;
