RedHat: RHSA-2017-3141:01 Important: rhvm-appliance security, bug fix,
Summary
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).
