Samba upgrade to version 3.6.3 fixes the following
security issue:
PIDL based autogenerated code allows overwriting beyond
of allocated array. Remove attackers could exploit that
to execute arbitrary code as root (CVE-2012-1182,
bso#8815, bnc#752797)
Please see /usr/share/doc/packages/samba/WHATSNEW.txt from
the samba-doc package or the package change log (rpm -q
–changelog samba) for more details of the version update.
