Summary
Red Hat Security Advisory: rhvm-appliance security, bug fix, and enhancement update

Notes

Topic
An update for rhvm-appliance is now available for Red Hat Virtualization 4 for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
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 (4.3). (BZ#1669364, BZ#1684987, BZ#1697231, BZ#1720255) Security Fix(es): * rsyslog: imptcp: integer overflow when Octet-Counted TCP Framing is enabled (CVE-2018-16881) * openssl: 0-byte record padding oracle (CVE-2019-1559) * undertow: leak credentials to log files UndertowLogger.REQUEST_LOGGER.undertowRequestFailed (CVE-2019-3888) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable \"non-stitched\" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). Fixed in OpenSSL 1.0.2r (Affected 1.0.2-1.0.2q).",
