The previous security update for samba introduced regressions in the handling of the depreciated filesystem smbfs. This update fixes the regression(s) whilst still fixing the security problems. The original text is reproduced below: Several local/remote vulnerabilities have been discovered in samba, a LanManager-like file and printer server for Unix. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2007-5398 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-2007-4572 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. For the stable distribution (etch), these problems have been fixed in version 3.0.24-6etch7. For the old stable distribution (sarge), these problems have been fixed in version 3.0.14a-3sarge9. For the unstable distribution (sid), these problems have been fixed in version 3.0.27-1. We recommend that you upgrade your samba packages.
