Security fix for CVE-2019-14822

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.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:3978 advisory.

    GLib provides the core application building blocks for libraries and applications written in C. It     provides the core object system used in GNOME, the main loop implementation, and a large set of utility     functions for strings and common data structures.

    The Intelligent Input Bus (IBus) is an input method framework for multilingual input in Unix-like     operating systems.

    Security Fix(es):

    * glib2: file_copy_fallback in gio/gfile.c in GNOME GLib does not properly restrict file permissions while     a copy operation is in progress (CVE-2019-12450)

    * ibus: missing authorization allows local attacker to access the input bus of another user     (CVE-2019-14822)

According to the version of the ibus packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - A flaw was discovered in ibus in versions before 1.5.22     that allows any unprivileged user to monitor and send     method calls to the ibus bus of another user due to a     misconfiguration in the DBus server setup. A local     attacker may use this flaw to intercept all keystrokes     of a victim user who is using the graphical interface,     change the input method engine, or modify other input     related configurations of the victim     user.(CVE-2019-14822)

The remote AlmaLinux 8 host has packages installed that are affected by a vulnerability as referenced in the ALSA-2020:1880 advisory.

  - A flaw was discovered in ibus in versions before 1.5.22 that allows any unprivileged user to monitor and     send method calls to the ibus bus of another user due to a misconfiguration in the DBus server setup. A     local attacker may use this flaw to intercept all keystrokes of a victim user who is using the graphical     interface, change the input method engine, or modify other input related configurations of the victim     user. (CVE-2019-14822)

The version of AOS installed on the remote host is prior to 5.19.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.19.1 advisory.

  - In Network Security Services (NSS) before 3.46, several cryptographic primitives had missing length     checks. In cases where the application calling the library did not perform a sanity check on the inputs it     could result in a crash due to a buffer overflow. (CVE-2019-17006)

  - Heap buffer overflow in the TFTP protocol handler in cURL 7.19.4 to 7.65.3. (CVE-2019-5482)

  - In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.
    When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may     contain files with permissions the attacker did not have or in paths he did not have access to. Extracting     those archives from a high-privilege user without carefully reviewing them may lead to the compromise of     the system. (CVE-2019-14866)

  - If an HTTP/2 client connecting to Apache Tomcat 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to     8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the     HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP     headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This     could lead to users seeing responses for unexpected resources. (CVE-2020-13943)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported     versions that are affected are 5.6.45 and prior, 5.7.27 and prior and 8.0.17 and prior. Easily exploitable     vulnerability allows low privileged attacker with network access via multiple protocols to compromise     MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang     or frequently repeatable crash (complete DOS) of MySQL Server. (CVE-2019-2974)

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has ibus packages installed that are affected by a vulnerability:

  - A flaw was discovered in ibus in versions before 1.5.22 that allows any unprivileged user to monitor and     send method calls to the ibus bus of another user due to a misconfiguration in the DBus server setup. A     local attacker may use this flaw to intercept all keystrokes of a victim user who is using the graphical     interface, change the input method engine, or modify other input related configurations of the victim     user.
