Please see these lines at PdfTokenizer::ReadString:
pdf_long outLen = m_vecBuffer.size() -
pEncrypt->CalculateStreamOffset();
char * outBuffer = new char[outLen];
pEncrypt->Decrypt( reinterpret_cast<unsigned
char*>(&(m_vecBuffer[0])),
static_cast<unsigned int>(m_vecBuffer.size()),
reinterpret_cast<unsigned char*>(outBuffer),
outLen);
The size may calculate incorrectly (too small). Underlying AES encoding
expects output buffer at least 16 bytes long (or divisible by 16 - I'm not
sure, the code is not so clear).
In my particular case "outLen" became equal 7 and buffer overrun happens in
AES_cbc_encrypt (in openssl). I hope you will be able to fix it soon.
Thank you.
