After my quick core dump analysis I'm quite sure that the problem comes from: glibc-2.17-4.4.1, nscd netgroupcache.c in line 205: size_t userlen = strlen (nuser) + 1; <------ core dump because nuser in the triple code is 0 in case of (host,,) entries in NIS! This may causes the core dump. I found two work arounds to avoid a nscd crash: 1.) switch off netgroup in nscd.conf enable-cache netgroup yes -> no or 2.) in NIS change entries in netgroup (host,,) -> (host,-,<youdomain> regards Thomas Reply at: https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/997096/comments/10 ------------------------------------------------------------------------ On 2013-07-04T15:03:19+00:00 E-kuemmerle wrote: I can confirm that bug, I observe exactly the same segfaults on my server: (gdb) where #0 0x00007f32fd360741 in __strlen_sse2_pminub () from /lib64/libc.so.6 #1 0x00007f32fde513cd in addgetnetgrentX (db=db@entry=0x7f32fe059640 <dbs+1440>, fd=fd@entry=-1, req=req@entry=0x7f32f19977a0, key=key@entry=0x7f32f19979e0 "asslgc", uid=uid@entry=4294967295, he=he@entry=0x0, dh=dh@entry=0x0, resultp=resultp@entry=0x7f32f1997798) at netgroupcache.c:205 #2 0x00007f32fde51eb5 in addinnetgrX (db=db@entry=0x7f32fe059640 <dbs+1440>, fd=fd@entry=15, req=req@entry=0x7f32f1997860, key=<optimized out>, key@entry=0x7f32f19979e0 "asslgc", uid=uid@entry=4294967295, he=he@entry=0x0, dh=dh@entry=0x0) at netgroupcache.c:487 #3 0x00007f32fde52074 in addinnetgr (db=db@entry=0x7f32fe059640 <dbs+1440>, fd=fd@entry=15, req=req@entry=0x7f32f1997860, key=key@entry=0x7f32f19979e0, uid=uid@entry=4294967295) at netgroupcache.c:652 #4 0x00007f32fde3ed36 in handle_request (pid=<optimized out>, key=0x7f32f19979e0, req=0x7f32f1997860, fd=15, uid=<optimized out>) at connections.c:1326 #5 nscd_run_worker (p=<optimized out>) at connections.c:1792 #6 0x00007f32fd9fde0f in start_thread () from /lib64/libpthread.so.0 #7 0x00007f32fd2f97dd in clone () from /lib64/libc.so.6 (gdb) print data.val.triple $3 = {host = 0x7f32f19971c8 "ass801", user = 0x0, domain = 0x0} Reply at: https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/997096/comments/11 ------------------------------------------------------------------------ On 2013-09-30T16:05:48+00:00 Swamp-a wrote: openSUSE-SU-2013:1510-1: An update that solves 6 vulnerabilities and has 5 fixes is now available.
