(RHSA-2017:3141) Important: rhvm-appliance security, bug fix, and enhancement update

The RHV-M Virtual Appliance automates the process of installing and configuring the Red Hat Virtualization Manager. The appliance is available to download as an OVA file from the Customer Portal.

The following packages have been upgraded to a later upstream version: rhvm-appliance (20171019.0). (BZ#1496586)

Security Fix(es):

• A deserialization flaw was discovered in the jackson-databind which could allow an unauthenticated user to perform code execution by sending the maliciously crafted input to the readValue method of the ObjectMapper. (CVE-2017-7525)

• A vulnerability was found in Jasypt that would allow an attacker to perform a timing attack on password hash comparison. (CVE-2014-9970)

• It was found that when the security manager’s reflective permissions, which allows it to access the private members of the class, are granted to Hibernate Validator, a potential privilege escalation can occur. By allowing the calling code to access those private members without the permission an attacker may be able to validate an invalid instance and access the private member value via ConstraintViolation#getInvalidValue(). (CVE-2017-7536)

Red Hat would like to thank Liao Xinxi (NSFOCUS) for reporting CVE-2017-7525. The CVE-2017-7536 issue was discovered by Gunnar Morling (Red Hat).
