Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
A regression was found in the fix for CVE-2011-3389/7064341 that was applied to Oracle JDK 6u29 and matching OpenJDK update.  This causes connections to certain SSL servers to hang:

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7103725

In our case, this problem was reported for JBoss products using JDBC to connect to Microsoft SQL server.  Some workarounds were identified:
- use non-CBC cipher (e.g. one of RC4 cipher suites)
- disable CVE-2011-3389 mitigation using -Djsse.enableCBCProtection=false

Oracle 6u30 was released to address this issue:

Fixed in upstream OpenJDK:

http://hg.openjdk.java.net/jdk6/jdk6/jdk/rev/cb20ed4b953a

Fix is in IcedTea6 HEAD:

http://icedtea.classpath.org/hg/icedtea6/rev/8a24f86753c6

Needs backporting to branches.

This is fixed in the latest upstream release:

http://blog.fuseyism.com/index.php/2012/01/12/icedtea6-1-8-12-1-9-12-and-1-10-5-released/

I'll leave others to comment on when this will be packaged for RHEL.

This was fixed upstream in IcedTea 1.10.5.  We have updated to 1.10.6 in RHSA-2012:0135, hence this issue is fixed.
