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: ‘key length too large’ (bnc#934299).
Take resource group sids into account when caching netsamlogon data (bnc#912457).
Use domain name if search by domain SID fails to send SIDHistory lookups to correct idmap backend (bnc#773464).
Remove deprecated base_rid example from idmap_rid manpage (bnc#913304).
Purge printer name cache on spoolss SetPrinter change (bnc#901813).
Fix lookup of groups with ‘Local Domain’ scope from Active Directory (bnc#948244).
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
