CVE-2019-5067 — An uninitialized memory access vulnerability exists in the way Aspose.PDF 19.2 for C++ handles invalid parent object pointers

Critical CVSS 9.8

An uninitialized memory access vulnerability exists in the way Aspose.PDF 19.2 for C++ handles invalid parent object pointers. A specially crafted PDF can cause a read and write from uninitialized memory, resulting in memory corruption and possibly arbitrary code execution. To trigger this vulnerability, a specifically crafted PDF document needs to be processed by the target application.

Use-after-free, double free, and expired resource use

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace ownership, references, callbacks, asynchronous tasks, and teardown paths around the affected object or resource.
  • Identify reachable inputs and timing or state transitions that can release the object while references remain.
  • Confirm affected builds, allocators, feature flags, architectures, and process privileges.

Remediate safely

  • Apply the maintained ownership or lifetime fix and rebuild all artifacts containing the affected native code.
  • Use explicit ownership, safe reference management, cancellation and join semantics, and idempotent teardown.
  • Add deterministic lifetime tests plus isolated sanitizer and concurrency coverage for shutdown and error paths.
