Hi,

The following vulnerability was published for dia.

CVE-2019-19451[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
