podofo is a C++ library to work with the PDF file format.
A fuzz on it with the UBSAN discovered a signed integer overflow. The upstream project denies me to open a new ticket. So, I’m unable to communicate with them.
The complete UBSan output:
# podofopdfinfo $FILE /tmp/portage/app-text/podofo-0.9.4/work/podofo-0.9.4/src/base/PdfParser.cpp:757:23: runtime error: signed integer overflow: 9223372036854775807 + 9 cannot be represented in type 'long'
