Ubuntu 6.06 LTS / 7.04 / 7.10 / 8.04 LTS : samba regression (USN-617-2)
High Nessus Plugin ID 33388
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionUSN-617-1 fixed vulnerabilities in Samba. The upstream patch introduced a regression where under certain circumstances accessing large files might cause the client to report an invalid packet length error. This update fixes the problem.
We apologize for the inconvenience.
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 Samba did not properly perform bounds checking when parsing SMB replies. A remote attacker could send crafted SMB packets and execute arbitrary code. (CVE-2008-1105).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected packages.
