A Segmentaation fault was found in UPX in invert_pt_dynamic() function in p_lx_elf.cpp. An attacker with a crafted input file allows invalid memory address access that could lead to a 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.
