Announcing IBM Z Development and Test Environment (IBM ZD&T) V12.0.5.2 fix pack. We had so many great ideas for 12.0, we couldn’t fit them all in one release. So today, we are excited to announce the release of 12.0.5.2 fix pack - APAR fixes.

Summary of the fixes:
The following security threats has been fixed. 
1. An unauthenticated attacker might be able to obtain the sensitive information due to an unspecified vulnerability that is related to the JSSE component in the Java SE. This defect caused a low confidentiality impact from unknown attack vectors. 
2. Hibernate Validator, which is used by WebSphere Application Server Liberty, could allow a remote attacker to bypass security restrictions. 

The following defects has been fixed. 
1. A deployment failed with a devmap problem that showed an error: AWSCHK075E Hexadecimal UNITADD value '100' invalid.
2. When you ran an SFTP command, some data in the messages.log was displayed by mistake.
3. When you ran an SFTP command to call zDTMainframeSFTP.jar, the data was not enclosed in the single quotation mark, which caused the command execution to be broken.
