Description OSIDB Bzimport 2025-02-12 14:23:50 UTC 
If XkbChangeTypesOfKey() is called with 0 group, it will resize the key
symbols table to 0 but leave the key actions unchanged.

If later, the same function is called with a non-zero value of groups,
this will cause a buffer overflow because the key actions are of the wrong
size.
