Package: libnss-mdns Version: 0.9-0.2 Severity: critical Tags: security I have two SPARC machines after latest upgrade apt install avahi-package and modify /etc/nsswitch.conf to use avahi. But now if I ping from one machine to second ping crasehd with SIGBUS. If I ping from second to first ping not crashed. Both machines runnig SID and are synced with repository. There is back trace of this: Core was generated by `ping e450'. Program terminated with signal 10, Bus error. #0 0xf7ef8b94 in _nss_mdns4_gethostbyaddr_r () from /lib/libnss_mdns4.so.2 (gdb) bt #0 0xf7ef8b94 in _nss_mdns4_gethostbyaddr_r () from /lib/libnss_mdns4.so.2 #1 0xf7e682c4 in gethostbyaddr_r@@GLIBC_2.1.2 () from /lib/libc.so.6 #2 0xf7e68064 in gethostbyaddr () from /lib/libc.so.6 #3 0x00011140 in ??

Please look to bug 413471 I spend some time to solve may be similar problem. This problem is only SPARC related and is caused by unaligned access to char buffer. When I stop avahi or modify /etc/nsswitch.conf to disable mdns4 and mdns4_minimal ping not crash. ssh,telnet,mysql crashed too but only when I ssh,mysql to machine from SPARC machine and not crash when use i386. -- System Information: Debian Release: lenny/sid APT prefers testing APT policy: (500, 'testing') Architecture: sparc (sparc64) Kernel: Linux 2.6.20 (SMP w/1 CPU core) Locale: LANG=cs_CZ, LC_CTYPE=cs_CZ (charmap=ISO-8859-2) Shell: /bin/sh linked to /bin/bash Versions of packages libnss-mdns depends on: ii avahi-daemon 0.6.16-5 Avahi mDNS/DNS-SD daemon ii base-files 4.0.0 Debian base system miscellaneous f ii libc6 2.5-3 GNU C Library: Shared libraries ii perl 5.8.8-7 Larry Wall's Practical Extraction libnss-mdns recommends no packages. -- debconf-show failed -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
