In Exiv2 0.26, the Exiv2::Internal::printCsLensFFFF function in canonmn_int.cpp allows remote attackers to cause a denial of service (invalid memory access) via a crafted file.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
