Adobe Acrobat and Reader versions 2019.021.20061 and earlier, 2017.011.30156 and earlier, 2017.011.30156 and earlier, and 2015.006.30508 and earlier have a stack exhaustion vulnerability. Successful exploitation could lead to memory leak .
Weakness
The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory.

Potential Mitigations
- Choose a language or tool that provides automatic memory management, or makes manual memory management less error-prone.
- For example, glibc in Linux provides protection against free of invalid pointers.
- When using Xcode to target OS X or iOS, enable automatic reference counting (ARC) [REF-391].
- To help correctly and consistently manage memory when programming in C++, consider using a smart pointer class such as std::auto_ptr (defined by ISO/IEC ISO/IEC 14882:2003), std::shared_ptr and std::unique_ptr (specified by an upcoming revision of the C++ standard, informally referred to as C++ 1x), or equivalent solutions such as Boost.
