[Bug 1270385] Re: Panic or segfault in Samba

[Marc Deslauriers]

Thanks for taking the time to report this bug and helping to make Ubuntu
better. We appreciate the difficulties you are facing, but this appears
to be a "regular" (non-security) bug.  I have unmarked it as a security
issue since this bug does not show evidence of allowing attackers to
cross privilege boundaries nor directly cause loss of data/privacy.
Please feel free to report any other bugs you may find.

** Information type changed from Private Security to Public

Title:
  Panic or segfault in Samba

Status in “samba” package in Ubuntu:
  New

Bug description:
  The Samba 'panic action' script, /usr/share/samba/panic-action,
  was called for PID 14296 (/usr/sbin/smbd).

  This means there was a problem with the program, such as a segfault.
  Below is a backtrace for this process generated with gdb, which shows
  the state of the program at the time the error occurred.  The Samba log
  files may contain additional information about the problem.

  If the problem persists, you are encouraged to first install the
  samba-dbg package, which contains the debugging symbols for the Samba
  binaries.  Then submit the provided information as a bug report to
  Ubuntu by visiting this link:
