high Nessus Plugin ID 194156

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:1436 advisory.

HAProxy is a TCP/HTTP reverse proxy which is particularly suited for high availability environments.

The following packages have been upgraded to a later upstream version: rh-haproxy18-haproxy (1.8.17).
(BZ#1660514)

Security Fix(es):

* haproxy: Infinite recursion via crafted packet allows stack exhaustion and denial of service (CVE-2018-20103)

* haproxy: Information disclosure in check_request_for_cacheability function in proto_http.c (CVE-2018-11469)

* haproxy: Out-of-bounds read in dns.c:dns_validate_dns_response() allows for memory disclosure (CVE-2018-20102)

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.

Bug Fix(es):

* ALPN is not enabled due to old OpenSSL dependancy (BZ#1595865)

* HAProxy 1.8: Seamless reload does not work with send-/accept-proxy (BZ#1649041)

Enhancement(s):

* RFE : Haproxy does not resolve ipv6 resolvable hostnames in the backend section. (BZ#1575585)

Additional Changes:

For detailed information on changes in this release, see the Red Hat Software Collections 3.3 Release Notes linked from the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected rh-haproxy18-haproxy and / or rh-haproxy18-haproxy-syspaths packages.
