A buffer overflow vulnerability exists in the PowerPoint document conversion function of Rainbow PDF Office Server Document Converter V7.0 Pro MR1 (7,0,2019,0220). While parsing a document text info container, the TxMasterStyleAtom::parse function is incorrectly checking the bounds corresponding to the number of style levels, causing a vtable pointer to be overwritten, which leads to code execution.
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().
The product writes data past the end, or before the beginning, of the intended buffer.
