keycloak-httpd-client-install versions before 0.8 insecurely creates temporary file allowing local attackers to overwrite other files via symbolic link.

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2019-2137 advisory.

    [0.8-1]
    - Resolves: rhbz#1673716 - Rebase k-h-c-i to version 0.8
    - The rebase also includes fixes for:
      - rhbz#1533190 - CVE-2017-15111 keycloak-httpd-client-install: unsafe                        /tmp log file in --log-file option in keycloak_cli.py
      - rhbz#1533202 - CVE-2017-15112 keycloak-httpd-client-install: unsafe                        use of -p/--admin-password on command line

Tenable has extracted the preceding description block directly from the Oracle 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.

It was discovered that keycloak-httpd-client-install uses a predictable log file name in /tmp. A local attacker could create a symbolic link to a sensitive location, possibly causing data corruption or denial of service.(CVE-2017-15111)

In keycloak-http-client-install prior to version 0.8, the admin password could be provided through a command-line argument. This might result in the password being leaked through shell history, or becoming visible to a local attacker at the time the program is running.(CVE-2017-15112)

An update for keycloak-httpd-client-install is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Low. 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.

The keycloak-httpd-client-install packages provide various libraries and tools that can automate and simplify the configuration of Apache httpd authentication modules when registering as a Red Hat Single Sign-On (RH-SSO, also called Keycloak) federated Identity Provider (IdP) client.

The following packages have been upgraded to a later upstream version:
keycloak-httpd-client-install (0.8). (BZ#1673716)

Security Fix(es) :

* keycloak-httpd-client-install: unsafe /tmp log file in --log-file option in keycloak_cli.py (CVE-2017-15111)

* keycloak-httpd-client-install: unsafe use of -p/--admin-password on command line (CVE-2017-15112)

Security fix for CVE-2017-15111, CVE-2017-15112

Two minor security issues were discovered and were assigned CVE's.
CVE-2017-15112 concerns the ability to pass a password on the command line where it could be exposed. That option has been deprecated. See the man page for multiple ways to pass the password. CVE-2017-15111 corrects the default location of a log file when running the low level utilities directly, it had placed the log file in /tmp where a symbolic link could be created pointing to another file. The risk with CVE-2017-15111 is very low as this feature is seldom used, it's mostly for developers.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
