Abstract
The JDKs TLS implementation may not check the TLS vector length as set out in
the Internet Engineering Task Force Request For Comments (RFC) 5246. The fix
enhances the checking for the vector length.
Content
VULNERABILITY DETAILS:
DESCRIPTION: The JDK's TLS implementation may not check the TLS vector length
as set out in the latest RFC 5246. This issue is exploitable on server
deployments that use JSSE.
A Java program running on Tivoli Directory Integrator uses Java Secure Socket
Extensions (JSSE) to establish the Secure Socket Layer (SSL) connection. The
vulnerability could occur when the SSL connection is enabled and only solution
is to upgrade the JRE.
The attack does not require local network access nor does it require
authentication. but some degree of specialized knowledge and techniques are
required. An exploit would not impact the confidentiality of information or
the integrity of data, however availability of the system could be
compromised.
