How to fix?

Upgrade SLES:15.0 dia-lang to version 0.97.3-4.3.3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream dia-lang package and not the dia-lang package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

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.
