========================================================================== Ubuntu Security Notice USN-2054-1 December 11, 2013
samba vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.10 - Ubuntu 13.04 - Ubuntu 12.10 - Ubuntu 12.04 LTS - Ubuntu 10.04 LTS
Summary:
Several security issues were fixed in Samba.
Software Description: - samba: SMB/CIFS file, print, and login server for Unix
Details:
It was discovered that Winbind incorrectly handled invalid group names with the require_membership_of parameter. If an administrator used an invalid group name by mistake, access was granted instead of having the login fail. (CVE-2012-6150)
Stefan Metzmacher and Michael Adam discovered that Samba incorrectly handled DCE-RPC fragment length fields. A remote attacker could use this issue to cause Samba to crash, resulting in a denial of service, or possibly execute arbitrary code as the root user. (CVE-2013-4408)
Hemanth Thummala discovered that Samba incorrectly handled file permissions when vfs_streams_depot or vfs_streams_xattr were enabled. A remote attacker could use this issue to bypass intended restrictions. (CVE-2013-4475)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 13.10: libpam-winbind 2:3.6.18-1ubuntu3.1 samba 2:3.6.18-1ubuntu3.1
Ubuntu 13.04: libpam-winbind 2:3.6.9-1ubuntu1.2 samba 2:3.6.9-1ubuntu1.2
Ubuntu 12.10: libpam-winbind 2:3.6.6-3ubuntu5.3 samba 2:3.6.6-3ubuntu5.3
Ubuntu 12.04 LTS: libpam-winbind 2:3.6.3-2ubuntu2.9 samba 2:3.6.3-2ubuntu2.9
Ubuntu 10.04 LTS: samba 2:3.4.7~dfsg-1ubuntu3.13 winbind 2:3.4.7~dfsg-1ubuntu3.13
In general, a standard system update will make all the necessary changes.
