Red Hat Security Advisory 2014-1320-01

Red Hat Security Advisory 2014-1320-01 – Red Hat JBoss Enterprise Web Platform is a platform for Java applications, which integrates the JBoss Web Server with JBoss Hibernate and JBoss Seam. It was found that the fix for CVE-2012-5783 was incomplete: the code added to check that the server host name matches the domain name in a subject’s Common Name field in X.509 certificates was flawed. A man-in-the-middle attacker could use this flaw to spoof an SSL server using a specially crafted X.509 certificate. It was discovered that the HttpClient incorrectly extracted host name from an X.509 certificate subject’s Common Name field. A man-in-the-middle attacker could use this flaw to spoof an SSL server using a specially crafted X.509 certificate.

CVE-2014-4330

The Dumper method in Data::Dumper before 2.154, as used in Perl 5.20.1 and earlier, allows context-dependent attackers to cause a denial of service (stack consumption and crash) via an Array-Reference with many nested Array-References, which triggers a large number of recursive calls to the DD_dump function. (CVSS:2.1) (Last Update:2014-10-01)

DSA-3040 rsyslog – security update

Rainer Gerhards, the rsyslog project leader, reported a vulnerability in
Rsyslog, a system for log processing. As a consequence of this
vulnerability an attacker can send malformed messages to a server, if
this one accepts data from untrusted sources, and trigger a denial of
service attack.
