================================================== ========= Ubuntu Security Notice USN-556-1 December 18, 2007 samba vulnerability CVE-2007-6015 ================================================== ========= A security issue affects the following Ubuntu releases: Ubuntu 6.06 LTS Ubuntu 6.10 Ubuntu 7.04 Ubuntu 7.10 This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu. The problem can be corrected by upgrading your system to the following package versions: Ubuntu 6.06 LTS: libsmbclient 3.0.22-1ubuntu3.6 samba 3.0.22-1ubuntu3.6 Ubuntu 6.10: libsmbclient 3.0.22-1ubuntu4.5 samba 3.0.22-1ubuntu4.5 Ubuntu 7.04: libsmbclient 3.0.24-2ubuntu1.5 samba 3.0.24-2ubuntu1.5 Ubuntu 7.10: libsmbclient 3.0.26a-1ubuntu2.3 samba 3.0.26a-1ubuntu2.3 In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: Alin Rad Pop discovered that Samba did not correctly check the size of reply packets to mailslot requests. If a server was configured with domain logon enabled, an unauthenticated remote attacker could send a specially crafted domain logon packet and execute arbitrary code or crash the Samba service. By default, domain logon is disabled in Ubuntu.
