Heap Buffer Overflow vulnerability in qpdf 11.9.0 allows attackers to crash the application via the std::__shared_count() function at /bits/shared_ptr_base.h.
The product writes data past the end, or before the beginning, of the intended buffer.
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
