An Invalid memory address dereference was discovered in Exiv2::getULong in types.cpp in Exiv2 0.26. The vulnerability causes a segmentation fault and application crash, which leads to denial of service.
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.
