Description Vasyl Kaigorodov 2014-12-25 11:54:04 UTC
Common Vulnerabilities and Exposures assigned an identifier CVE-2014-3569 to
the following vulnerability:

Name: CVE-2014-3569
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3569
Assigned: 20140514
Reference: https://security-tracker.debian.org/tracker/CVE-2014-3569

The ssl23_get_client_hello function in s23_srvr.c in OpenSSL 1.0.1j
does not properly handle attempts to use unsupported protocols, which
allows remote attackers to cause a denial of service (NULL pointer
dereference and daemon crash) via an unexpected handshake, as
demonstrated by an SSLv3 handshake to a no-ssl3 application with
certain error handling.  NOTE: this issue became relevant after the
CVE-2014-3568 fix.


Not vulnerable. The versions of openssl package as shipped in Red Hat Enterprise Linux 5, 6 and 7; Red Hat JBoss Enterprise Application Platform 5 and 6; and Red Hat JBoss Enterprise Web Server 1 and 2 are not vulnerable to CVE-2014-3568, therefore does not have CVE-2014-3568 fix applied, and therefore are not vulnerable to this security flaw.
