New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote VMware ESX host is missing a security-related patch.
DescriptionThe remote VMware ESX host is missing a security-related patch. It is, therefore, affected by multiple vulnerabilities in several third-party components and libraries :
- A denial of service vulnerability exists in the ACPI Event Daemon (acpid) that allows a remote attacker to cause a consumption of CPU resources by opening a large number of UNIX sockets without closing them.
- A security bypass vulnerability exists in Samba in the acl_group_override() function when dos filemode is enabled. A remote attacker can exploit this to modify access control lists for files via vectors related to read access to uninitialized memory. (CVE-2009-1888)
- A security bypass vulnerability exists in Samba in the SMB subsystem due to improper handling of errors when resolving pathnames. An authenticated, remote attacker can exploit this to bypass intended sharing restrictions, and read, create, or modify files, in certain circumstances involving user accounts that lack home directories. (CVE-2009-2813)
- A denial of service vulnerability exists in Samba that allows authenticated, remote attackers to cause an infinite loop via an unanticipated oplock break notification reply packet. (CVE-2009-2906)
- An information disclosure vulnerability exists in Samba in mount.cifs due to improper enforcement of permissions. A local attacker can exploit this to read part of the credentials file and obtain the password by specifying the path to the credentials file and using the --verbose or -v option. (CVE-2009-2948)
SolutionApply the appropriate patch according to the vendor advisory that pertains to ESX version 4.0.
