Description

The Samba 2:3.6.6-6+deb7u9 release, issued by the DSA-3548-1, introduced different regressions causing trust relationship with Win 7 domains to fail. The fix for the CVE-2016-2115 has been reverted, so administrators should set 'client signing = required' instead.

For Debian 7 'Wheezy', these problems have been fixed in version 2:3.6.6-6+deb7u10. More information is available in the NEWS file included in this samba release.

We recommend that you upgrade your samba packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
