- EPSS: 0.4% probability of exploitation in the next 30 days
- Public exploit or detection template: none known

- Weakness: CWE-835
Description
When GNOME Dia before 2019-11-27 is launched with a filename argument that is not a valid codepoint in the current encoding, it enters an endless loop, thus endlessly writing text to stdout. If this launch is from a thumbnailer service, this output will usually be written to disk via the system's logging facility (potentially with elevated privileges), thus filling up the disk and eventually rendering the system unusable. (The filename can be for a nonexistent file.) NOTE: this does not affect an upstream release, but affects certain Linux distribution packages with version numbers such as 0.97.3.
Affected products
- Fedoraproject Fedora: 32, 33
- GNOME Dia: before 2019-11-27 — fixed in 2019-11-27
- openSUSE Leap: 15.1
How to fix
Upgrade to a fixed version: GNOME Dia 2019-11-27. Check the vendor advisory for mitigations.
