Description

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 6.4.5 serves as a replacement for Red Hat JBoss BRMS 6.4.4, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References.

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)
  • An XXE vulnerability was found in Apache Batik which could allow a remote attacker to retrieve the files on the vulnerable server's filesystem by uploading specially crafted SVG images. The vulnerability could also allow a denial of service condition by performing an amplification attack. (CVE-2017-5662)

Red Hat would like to thank Liao Xinxi (NSFOCUS) for reporting CVE-2017-7525.
