SB2024041288 - openEuler 22.03 LTS SP2 update for flatpak

Description

This security bulletin contains information about 3 secuirty vulnerabilities.

1) Input validation error (CVE-ID: CVE-2023-28100)

The vulnerability allows a malicious application to compromise the affected system.

The vulnerability exists due to insufficient validation of user-supplied input when handling copy/paste operations. If a Flatpak app is run on a Linux virtual console such as `/dev/tty1`, it can copy text from the virtual console and paste it into the command buffer, from which the command might be run after the Flatpak app has exited.

2) Input validation error (CVE-ID: CVE-2023-28101)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to insufficient validation of user-supplied input when displaying permissions and metadata. A remote attacker can create a specially crafted app that manipulates the appearance of the permissions list through metadata, convincing the user into granting to the app more permissions than agreed by the user.

3) Input validation error (CVE-ID: CVE-2017-5226)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to insufficient validation of user-supplied input. The non-privileged session can escape to the parent session by using the TIOCSTI ioctl to push characters into the terminal's input buffer, allowing an attacker to escape the sandbox.

Remediation
