Summary: Updated service console patches 2. Relevant releases: ESX Server 3.0.2 without patches ESX-1002969, ESX-1002970, ESX-1002971, ESX-1002975, ESX-1002976 ESX Server 3.0.1 without patches ESX-1002962, ESX-1002963, ESX-1002964, ESX-1002968, ESX-1002972, ESX-1003176 3. Problem description: I OpenPegasus PAM Authentication Buffer Overflow Alexander Sotirov from VMware Security Research discovered a buffer overflow vulnerability in the OpenPegasus Management server. This flaw could be exploited by a malicious remote user on the service console network to gain root access to the service console. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2007-5360 to this issue. RPM Updated: pegasus-2.5-552927 VM Shutdown: No Host Reboot: No Note: ESX Server 3.5 and ESX Server 3i are not affected by this issue. ESX Server 3.0.2 http://download3.vmware.com/software/vi/ESX-1002970.tgz md5sum: d19115e965d486e72100ce489efea707 http://kb.vmware.com/kb/1002970 ESX Server 3.0.1 http://download3.vmware.com/software/vi/ESX-1003176.tgz md5sum: 5674ca0dcfac90726014cc316444996e http://kb.vmware.com/kb/1003176 ESX Server 2.5.x Users should remove the OpenPegasus CIM Management rpm. This component is disabled by default, and VMware recommends that you do not use this component of ESX Server 2.x. If you want to use the CIM functionality, upgrade to ESX Server 3.0.1 or a later release. Note: This vulnerability can be exploited remotely only if the attacker has access to the service console network. Security best practices provided by VMware recommend that the service console be isolated from the VM network. Please see http://www.vmware.com/resources/techresources/726 for more information on VMware security best practices. II Service Console package security updates a. Updated Samba package An issue where attackers on the service console management network can cause a stack-based buffer overflow in the reply_netbios_packet function of nmbd in Samba. On systems where Samba is being used as a WINS server, exploiting this vulnerability can allow remote attackers to execute arbitrary code via crafted WINS Name Registration requests followed by a WINS Name Query request. An issue where attackers on the service console management network can exploit a vulnerability that occurs when Samba is configured as a Primary or Backup Domain controller. The vulnerability allows remote attackers to have an unknown impact via crafted GETDC mailslot requests, related to handling of GETDC logon server requests. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2007-5398 and CVE-2007-4572 to these issues. Note: By default Samba is not configured as a WINS server or a domain controller and ESX is not vulnerable unless the administrator has changed the default configuration. This vulnerability can be exploited remotely only if the attacker has access to the service console network. Security best practices provided by VMware recommend that the service console be isolated from the VM network. Please see http://www.vmware.com/resources/techresources/726 for more information on VMware security best practices.

Updated util-linux package The patch addresses an issue where the mount and umount utilities in util-linux call the setuid and setgid functions in the wrong order and do not check the return values, which could allow attackers to gain elevated privileges via helper application such as mount.nfs. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2007-5191 to this issue.

Updated Perl package The update addresses an issue where the regular expression engine in Perl can be used to issue a specially crafted regular expression that allows the attacker to run arbitrary code with the permissions level of the current Perl user. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2007-5116 to this issue.

Updated OpenSSL package A flaw in the SSL_get_shared_ciphers() function can allow an attacker to cause a buffer overflow problem by sending ciphers to applications that use the function. A possible vulnerability that would allow a local attacker to obtain private RSA keys being used on a system using the OpenSSL package. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2007-3108, and CVE-2007-5135 to these issues.
