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-2012-2733 [MEDIUM] Tomcat vulnerabilities
Title: Tomcat vulnerabilities
Summary: Several security issues were fixed in Apache Tomcat.
It was discovered that the Apache Tomcat HTTP NIO connector incorrectly
handled header data. A remote attacker could cause a denial of service by
sending requests with a large amount of header data. (CVE-2012-2733)
It was discovered that Apache Tomcat incorrectly handled DIGEST
authentication. A remote attacker could possibly use these flaws to perform
a replay attack and bypass authentication. (CVE-2012-5885, CVE-2012-5886,
CVE-2012-5887)
Instructions: In general, a standard system update will make all the necessary changes.

CVE-2012-2733 tomcat: HTTP NIO connector OOM DoS via a request with large headers
A denial of service flaw was found in the way Tomcat's HTTP NIO connector enforced limits on the permitted size of request headers. A remote attacker could use this flaw to trigger an OutOfMemoryError by sending a specially-crafted request with very large headers.
This flaw affects all versions of Tomcat up to 6.0.35 [1] and 7.0.27 [2].
