Folks, I am pleased to announce that the Apache Hadoop community has voted to release Apache Hadoop 2.5.2 <http://hadoop.apache.org/releases.html#19+November%2C+2014%3A+Release+2.5.2+available>, a point release that fixes two critical security issues - (1) CVE-2014-3566 <http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-3566>: Poodle vulnerability, and (2) CVE-2014-3627: a distributed-cache vulnerability (more details below). We encourage users to upgrade. Please see the release notes for more details.
Close on the heels of this, the community is planning to release a more feature-rich release in Hadoop-2.6.0, which is intended to be the last minor release that supports Java 6. Thanks Karthik --- CVE-2014-3627: Apache Hadoop distributed cache vulnerability Severity: Severe Vendor: The Apache Software Foundation Versions Affected: Hadoop 0.23.0 to 0.23.11 Hadoop 2.0.0 to 2.5.1 Users affected: Users running the YARN NodeManager daemon with Kerberos authentication Impact: Vulnerability allows a cluster user to expose private files owned by the user running the YARN NodeManager process. The malicious cluster user can create a public tar archive containing a symlink to a local file on the node owned by the user running the YARN NodeManager process. The permissions of the local file will be changed to be world-readable when the public archive is localized on the node. Mitigation: Users should upgrade to 2.5.2.
