This update for Samba fixes the following security issues :

  • CVE-2015-5330: Remote read memory exploit in LDB (bnc#958586).

  • CVE-2015-5252: Insufficient symlink verification (file access outside the share) (bnc#958582).

  • CVE-2015-5296: No man in the middle protection when forcing smb encryption on the client side (bnc#958584).

  • CVE-2015-5299: Currently the snapshot browsing is not secure thru windows previous version (shadow_copy2) (bnc#958583).

Non-security issues fixed :

  • Prevent NULL pointer access in samlogon fallback when security credentials are null (bnc#949022).

  • Address unrecoverable winbind failure:
