AlmaLinux 8 : qt5-qtbase and qt5-qtwebsockets (ALSA-2020:4690)

high Nessus Plugin ID 157637

Synopsis

The remote AlmaLinux host is missing one or more security updates.

Description

The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2020:4690 advisory.

- Qt through 5.14 allows an exponential XML entity expansion attack via a crafted SVG document that is mishandled in QXmlStreamReader, a related issue to CVE-2003-1564. (CVE-2015-9541)

- In Qt through 5.14.1, the WebSocket implementation accepts up to 2GB for frames and 2GB for messages.
Smaller limits cannot be configured. This makes it easier for attackers to cause a denial of service (memory consumption). (CVE-2018-21035)

- Out of bounds write in Intel(R) PROSet/Wireless WiFi products on Windows 10 may allow an authenticated user to potentially enable denial of service via local access. (CVE-2020-0569)

- Uncontrolled search path in the QT Library before 5.14.0, 5.12.7 and 5.9.10 may allow an authenticated user to potentially enable elevation of privilege via local access. (CVE-2020-0570)

- Qt 5.12.2 through 5.14.2, as used in unofficial builds of Mumble 1.3.0 and other products, mishandles OpenSSL's error queue, which can cause a denial of service to QSslSocket users. Because errors leak in unrelated TLS sessions, an unrelated session may be disconnected when any handshake fails. (Mumble 1.3.1 is not affected, regardless of the Qt version.) (CVE-2020-13962)

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

Solution

Update the affected qt5-qtbase-static and / or qt5-qttools-static packages.
