Description: Ghidra 10.2 through 12.1.4 contains a denial of service vulnerability in the ELF loader's ElfHeader class that allocates arrays sized by unvalidated extended section and program header counts. Attackers can supply a crafted 128-byte ELF file that triggers an OutOfMemoryError during load-spec discovery at import or in headless analysis pipelines.
