USN-544-1 fixed two vulnerabilities in Samba. Fixes for CVE-2007-5398
are unchanged, but the upstream changes for CVE-2007-4572 introduced a
regression in all releases which caused Linux smbfs mounts to fail.
Additionally, Dapper and Edgy included an incomplete patch which caused
configurations using NetBIOS to fail. A proper fix for these regressions
does not exist at this time, and so the patch addressing CVE-2007-4572
has been removed. This vulnerability is believed to be an unexploitable
denial of service, but a future update will address this issue. We
apologize for the inconvenience.
Original advisory details:
Samba developers discovered that nmbd could be made to overrun
a buffer during the processing of GETDC logon server requests.
When samba is configured as a Primary or Backup Domain Controller,
a remote attacker could send malicious logon requests and possibly
cause a denial of service. (CVE-2007-4572)
Alin Rad Pop of Secunia Research discovered that nmbd did not properly
check the length of netbios packets. When samba is configured as a WINS
server, a remote attacker could send multiple crafted requests resulting
in the execution of arbitrary code with root privileges. (CVE-2007-5398)
