RedHat: RHSA-2017-2888:01 Important: Red Hat JBoss BRMS 6.4.6 security
Summary
Red Hat JBoss BRMS is a business rules management system for the
management, storage, creation, modification, and deployment of JBoss Rules.
This release of Red Hat JBoss BRMS 6.4.6 serves as a replacement for Red
Hat JBoss BRMS 6.4.5, and includes bug fixes and enhancements, which are
documented in the Release Notes document linked to in the References.
Security Fix(es):
* It was found that when using remote logging with log4j socket server the
log4j server would deserialize any log event received via TCP or UDP. An
attacker could use this flaw to send a specially crafted log event that,
during deserialization, would execute arbitrary code in the context of the
logger application. (CVE-2017-5645)
* It was found that XStream contains a vulnerability that allows a
maliciously crafted file to be parsed successfully which could cause an
application crash. The crash occurs if the file that is being fed into
XStream input stream contains an instances of the primitive type 'void'. An
attacker could use this flaw to create a denial of service on the target
system. (CVE-2017-7957)
