An invalid memory address reference was discovered in the adjABS function in p_lx_elf.cpp in UPX 4.0.0 via a crafted Mach-O 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.
The product attempts to return a memory resource to the system, but it calls the wrong release function or calls the appropriate release function incorrectly.
