Description

Podofo v0.10.0 was discovered to contain a heap-use-after-free via the component PoDoFo::PdfEncrypt::IsMetadataEncrypted().

• CWE-416Use After FreeThe product reuses or references memory after it has been freed.

Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
