CVE-2012-2337 [HIGH] VMware security updates for vCenter Server
VMSA-2013-0006: VMware security updates for vCenter Server
a. vCenter Server AD anonymous LDAP binding credential by-pass vCenter Server when deployed in an environment that uses Active Directory (AD) with anonymous LDAP binding enabled doesn't properly handle login credentials. In this environment, authenticating to vCenter Server with a valid user name and a blank password may be successful even if a non-blank password is required for the account. The issue is present on vCenter Server 5.1, 5.1a and 5.1b if AD anonymous LDAP binding is enabled. The issue is addressed in vCenter Server 5.1 Update 1 by removing the possibility to authenticate using blank passwords. This change in the authentication mechanism is present regardless if anonymous binding is enabled or not.

CVE-2012-3546 [MEDIUM] Tomcat vulnerabilities
Title: Tomcat vulnerabilities
Summary: Several security issues were fixed in Tomcat.
It was discovered that Tomcat incorrectly performed certain security
constraint checks in the FORM authenticator. A remote attacker could
possibly use this flaw with a specially-crafted URI to bypass security
constraint checks. This issue only affected Ubuntu 10.04 LTS, Ubuntu 11.10
and Ubuntu 12.04 LTS. (CVE-2012-3546)
It was discovered that Tomcat incorrectly handled requests that lack a
session identifier. A remote attacker could possibly use this flaw to
bypass the cross-site request forgery protection. (CVE-2012-4431)
It was discovered that Tomcat incorrectly handled sendfile and HTTPS when
the NIO connector is used. A remote attacker could use this flaw to cause
Tomcat to stop responsing, resulti
