Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Input validation error
EUVDB-ID: #VU73835
Risk: Low
CVSSv3.1: 5.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-28100
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe 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
EUVDB-ID: #VU73834
Risk: Medium
CVSSv3.1: 4.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-28101
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe 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
EUVDB-ID: #VU73856
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
