Risk: Low
CVSSv4.0: 0.4 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2019-12450
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to the application applies default directory permissions to files while copying them in file_copy_fallback() function in gio/gfile.c. A local user can interfere with the copying operation and gain access to otherwise restricted files, as the application applies correct access permissions after the file was copied only.
Such application behavior allows a local user to access potentially sensitive data or modify file contents in case directory permissions that were applied to the file allow such operations.
Update the affected packages.
glib2.0 (Ubuntu package): 2.32.0-1 - 2.40.0-4
