- affected>= 1.0 and < 9.3.0.2
- affected>= 9.4.0.0 and < 9.4.0.1
As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
