That Nasty Samba Vulnerability Is Now Patched in All Supported Ubuntu Releases

According to the bug report, it would appear that Samba incorrectly handled shared libraries, thus allowing a remote attacker to upload a shared library to a writable share and then execute code on the affected, unpatched machines. The security flaw affects all Samba releases from version 3.5.0 onwards. The Samba team managed to quickly patch the critical vulnerability that was discovered to affect over a hundred thousand Linux and UNIX machines running Samba, which is usually used to provide file and printing sharing services, allowing users to connect to Windows shares on a network.
