RHEL 8 : qt5-qtbase and qt5-qtwebsockets (RHSA-2020:4690)

high Nessus Plugin ID 142445

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for qt5-qtbase / qt5-qtwebsockets.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:4690 advisory.

Qt is a software toolkit for developing applications. The qt5-base packages contain base tools for string, xml, and network handling in Qt.

Security Fix(es):

* qt: XML entity expansion vulnerability (CVE-2015-9541)

* qt5-qtwebsockets: websocket implementation allows only limited size for frames and messages therefore attacker can cause DOS (CVE-2018-21035)

* qt: files placed by attacker can influence the working directory and lead to malicious code execution (CVE-2020-0569)

* qt: files placed by attacker can influence the working directory and lead to malicious code execution (CVE-2020-0570)

* qt5: incorrectly calls SSL_shutdown() in OpenSSL mid-handshake causing denial of service in TLS applications (CVE-2020-13962)

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.

Additional Changes:

For detailed information on changes in this release, see the Red Hat Enterprise Linux 8.3 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 RHEL qt5-qtbase / qt5-qtwebsockets packages based on the guidance in RHSA-2020:4690.
