poppler: fix CVE-2021-30860
An integer overflow was addressed with improved input validation. This
issue is fixed in Security Update 2021-005 Catalina, iOS 14.8 and iPadOS
14.8, macOS Big Sur 11.6, watchOS 7.6.2. Processing a maliciously crafted
PDF may lead to arbitrary code execution. Apple is aware of a report that
this issue may have been actively exploited.
