java security update

CentOS Errata and Security Advisory CESA-2010:0768

These packages provide the OpenJDK 6 Java Runtime Environment and the
OpenJDK 6 Software Development Kit.

defaultReadObject of the Serialization API could be tricked into setting a
volatile field multiple times, which could allow a remote attacker to
execute arbitrary code with the privileges of the user running the applet
or application. (CVE-2010-3569)

Race condition in the way objects were deserialized could allow an
untrusted applet or application to misuse the privileges of the user
running the applet or application. (CVE-2010-3568)

Miscalculation in the OpenType font rendering implementation caused
out-of-bounds memory access, which could allow remote attackers to execute
code with the privileges of the user running the java process.
(CVE-2010-3567)

JPEGImageWriter.writeImage in the imageio API improperly checked certain
image metadata, which could allow a remote attacker to execute arbitrary
code in the context of the user running the applet or application.
(CVE-2010-3565)

Double free in IndexColorModel could cause an untrusted applet or
application to crash or, possibly, execute arbitrary code with the
privileges of the user running the applet or application. (CVE-2010-3562)

The privileged accept method of the ServerSocket class in the Common Object
Request Broker Architecture (CORBA) implementation in OpenJDK allowed it to
receive connections from any host, instead of just the host of the current
connection. An attacker could use this flaw to bypass restrictions defined
by network permissions. (CVE-2010-3561)

Flaws in the Swing library could allow an untrusted application to modify
the behavior and state of certain JDK classes. (CVE-2010-3557)

Flaws in the CORBA implementation could allow an attacker to execute
arbitrary code by misusing permissions granted to certain system objects.
(CVE-2010-3554)

UIDefault.ProxyLazyValue had unsafe reflection usage, allowing untrusted
callers to create objects via ProxyLazyValue values. (CVE-2010-3553)

HttpURLConnection improperly handled the “chunked” transfer encoding
method, which could allow remote attackers to conduct HTTP response
splitting attacks. (CVE-2010-3549)

HttpURLConnection improperly checked whether the calling code was granted
the “allowHttpTrace” permission, allowing untrusted code to create HTTP
TRACE requests. (CVE-2010-3574)

HttpURLConnection did not validate request headers set by applets, which
could allow remote attackers to trigger actions otherwise restricted to
HTTP clients. (CVE-2010-3541, CVE-2010-3573)

The Kerberos implementation improperly checked the sanity of AP-REQ
requests, which could cause a denial of service condition in the receiving
Java Virtual Machine. (CVE-2010-3564)

The RHSA-2010:0339 update mitigated a man-in-the-middle attack in the way
the TLS/SSL (Transport Layer Security/Secure Sockets Layer) protocols
handle session renegotiation by disabling renegotiation. This update
implements the TLS Renegotiation Indication Extension as defined in RFC
5746, allowing secure renegotiation between updated clients and servers.
(CVE-2009-3555)

The NetworkInterface class improperly checked the network “connect”
permissions for local network addresses, which could allow remote attackers
to read local network addresses. (CVE-2010-3551)

Information leak flaw in the Java Naming and Directory Interface (JNDI)
could allow a remote attacker to access information about
otherwise-protected internal network names. (CVE-2010-3548)

Note: Flaws concerning applets in this advisory (CVE-2010-3568,
CVE-2010-3554, CVE-2009-3555, CVE-2010-3562, CVE-2010-3557, CVE-2010-3548,
CVE-2010-3564, CVE-2010-3565, CVE-2010-3569) can only be triggered in
OpenJDK by calling the “appletviewer” application.

Bug fixes:

• This update provides one defense in depth patch. (BZ#639922)

• Problems for certain SSL connections. In a reported case, this prevented
  the JBoss JAAS modules from connecting over SSL to Microsoft Active
  Directory servers. (BZ#618290)
