[opensuse-factory] Buffer Overflows
  • From: Warren Stockton <wns@xxxxxxxxxxx>

I noticed that I am encountering a few "buffer overflows" but I don't see any
relevant reports in bugzilla, so it might be something specific to my
system. Could someone confirm before I enter a bunch of bugs?

The two executables that come to mind, are /usr/bin/dvd+rw-format
and /usr/sbin/bacula-fd but I have seen a few others as well... This is on
x86_64 with "latest" packages from Factory.

# dvd+rw-format
