Cloudera Technical Service Bulletin 2017-226 (TSB): Impala Statestore exposes plaintext data with SSL TLS enabled

Title: Impala Statestore exposes plaintext data with SSL TLS enabled 

During a security analysis, Cloudera found that despite TLS being enabled for “internal” Impala ports, the Statestore thrift port did not actually use TLS. This gap would allow an adversary with network access to eavesdrop and potentially modify the packets going to and coming from that port.

Products affected: Impala

Releases affected:
CDH 5.7 and lower
CDH 5.8.0, 5.8.1, 5.8.2, 5.8.3, 5.8.4
CDH 5.9.0, 5.9.1, 5.9.2
CDH 5.10.0, 5.10.1
CDH 5.11.0

Users affected: Deployments that use “internal” TLS (TLS between Impala daemons).

Date/time of detection: April 27, 2017

Detected by: Cloudera

Severity (Low/Medium/High): High

Impact: Data on the wire may be intercepted by a malicious server.

CVE: CVE-2017-5652

Immediate action required: Affected customers should upgrade to latest maintenance version with the fix.

Addressed in release/refresh/patch:
CDH 5.8.5, CDH 5.9.3, CDH 5.10.2, CDH 5.11.1, CDH 5.12.0

Cloudera Technical Service Bulletin 2017-249: Unsafe deserialization in Apache Spark launcher API

Title: Unsafe deserialization in Apache Spark launcher API 

In Apache Spark 1.6.0 until 2.1.1, the launcher API performs unsafe deserialization of data received by its socket. This makes applications launched programmatically using the SparkLauncher#startApplication() API potentially vulnerable to arbitrary code execution by an attacker with access to any user account on the local machine. It does not affect apps run by spark-submit or spark-shell. The attacker would be able to execute code as the user that ran the Spark application. Users are encouraged to update to Spark version 2.2.0 or later.

Products affected: Cloudera's distribution of Apache Spark and Spark in CDH.

Releases affected: 

• CDH: 5.9.0-5.9.2, 5.10.0-5.10.1, 5.11.0-5.11.1
• Cloudera's Distribution of Apache Spark: 2.0 Release 1, 2.0 Release 2, 2.1 Release 1

Users affected: All

Date/time of detection: June 1, 2017

Detected by: Aditya Sharad (Semmle)

Severity (Low/Medium/High): Medium

Impact: Privilege escalation to the user who ran the Spark application

CVE: CVE-2017-12612

Immediate action required: 

• Spark 1.x users: update to CDH 5.9.3, 5.10.2, 5.11.2, or 5.12.0 or later
• Spark 2.x users: update to Cloudera's Distribution of Apache Spark 2.2 Release 1 or later
• Or, discontinue use of the programmatic launcher API

Addressed in release/refresh/patch: 

• CDH: 5.9.3, 5.10.2, 5.11.2, 5.12.0
• Cloudera's Distribution of Apache Spark: 2.2 Release 1
