OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly restrict processing of ChangeCipherSpec messages, which allows man-in-the-middle attackers to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, and consequently hijack sessions or obtain sensitive information, via a crafted TLS handshake, aka the "CCS Injection" vulnerability.

JBoss Web, as used in Red Hat JBoss Communications Platform before 5.1.3, Enterprise Web Platform before 5.1.2, Enterprise Application Platform before 5.1.2, and other products, allows remote attackers to cause a denial of service (infinite loop) via vectors related to a crafted UTF-8 and a "surrogate pair character" that is "at the boundary of an internal buffer."

The org.jboss.remoting.transport.socket.ServerThread class in Red Hat JBoss Remoting for Red Hat JBoss SOA Platform 5.3.1 GA, Web Platform 5.2.0, Enterprise Application Platform 5.2.0, and other products allows remote attackers to cause a denial of service (file descriptor consumption) via unspecified vectors.

Apache CXF 2.5.x before 2.5.10, 2.6.x before CXF 2.6.7, and 2.7.x before CXF 2.7.4 does not verify that a specified cryptographic algorithm is allowed by the WS-SecurityPolicy AlgorithmSuite definition before decrypting, which allows remote attackers to force CXF to use weaker cryptographic algorithms than intended and makes it easier to decrypt communications, aka "XML Encryption backwards compatibility attack."

wsf/common/DOMUtils.java in JBossWS Native in Red Hat JBoss Enterprise Application Platform 4.2.0.CP09, 4.3, and 5.1.1; JBoss Enterprise Portal Platform 4.3.CP06 and 5.1.1; JBoss Enterprise SOA Platform 4.2.CP05, 4.3.CP05, and 5.1.0; JBoss Communications Platform 1.2.11 and 5.1.1; JBoss Enterprise BRMS Platform 5.1.0; and JBoss Enterprise Web Platform 5.1.1 does not properly handle recursion during entity expansion, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a crafted request containing an XML document with a DOCTYPE declaration and a large number of nested entity references, a similar issue to CVE-2003-1564.

ResourceBuilderImpl.java in the RichFaces 3.x through 5.x implementation in Red Hat JBoss Web Framework Kit before 2.3.0, Red Hat JBoss Web Platform through 5.2.0, Red Hat JBoss Enterprise Application Platform through 4.3.0 CP10 and 5.x through 5.2.0, Red Hat JBoss BRMS through 5.3.1, Red Hat JBoss SOA Platform through 4.3.0 CP05 and 5.x through 5.3.1, Red Hat JBoss Portal through 4.3 CP07 and 5.x through 5.2.2, and Red Hat JBoss Operations Network through 2.4.2 and 3.x through 3.1.2 does not restrict the classes for which deserialization methods can be called, which allows remote attackers to execute arbitrary code via crafted serialized data.

The default configuration of the (1) LdapLoginModule and (2) LdapExtLoginModule modules in JBoss Enterprise Application Platform (EAP) 4.3.0 CP10, 5.2.0, and 6.0.1, and Enterprise Web Platform (EWP) 5.2.0 allow remote attackers to bypass authentication via an empty password.

The GUI installer in JBoss Enterprise Application Platform (EAP) and Enterprise Web Platform (EWP) 5.2.0 and possibly 5.1.2 uses world-readable permissions for the auto-install XML file, which allows local users to obtain the administrator password and the sucker password by reading this file.

The CallerIdentityLoginModule in JBoss Enterprise Application Platform (EAP) before 5.2.0, Web Platform (EWP) before 5.2.0, BRMS Platform before 5.3.1, and SOA Platform before 5.3.1 allows remote attackers to gain privileges of the previous user via a null password, which causes the previous user's password to be used.

The (1) JMXInvokerHAServlet and (2) EJBInvokerHAServlet invoker servlets in JBoss Enterprise Application Platform (EAP) before 5.2.0, Web Platform (EWP) before 5.2.0, BRMS Platform before 5.3.1, and SOA Platform before 5.3.1 do not require authentication by default in certain profiles, which might allow remote attackers to invoke MBean methods and execute arbitrary code via unspecified vectors. NOTE: this issue can only be exploited when the interceptor is not properly configured with a "second layer of authentication," or when used in conjunction with other vulnerabilities that bypass this second layer.
