  "message": "PR30326, uninitialised value in objdump compare_relocs\n\nThis is a fuzzing PR, with a testcase involving a SHF_ALLOC and\nSHF_COMPRESSED SHT_RELA section, ie. a compressed dynamic reloc\nsection.  BFD doesn\u0027t handle compressed relocation sections, with most\nof the code reading relocs using sh_size (often no bfd section is\ncreated) but in the case of SHF_ALLOC dynamic relocs we had some code\nusing the bfd section size.  This led to a mismatch, sh_size is\ncompressed, size is uncompressed, and from that some uninitialised\nmemory.  Consistently using sh_size is enough to fix this PR, but I\u0027ve\nalso added tests to exclude SHF_COMPRESSED reloc sections from\nconsideration.\n\n\tPR 30362\n\t* elf.c (bfd_section_from_shdr): Exclude reloc sections with\n\tSHF_COMPRESSED flag from normal reloc processing.\n\t(_bfd_elf_get_dynamic_reloc_upper_bound): Similarly exclude\n\tSHF_COMPRESSED sections from consideration.  Use sh_size when\n\tsizing to match slurp_relocs.\n\t(_bfd_elf_canonicalize_dynamic_reloc): Likewise.\n\t(_bfd_elf_get_synthetic_symtab): Use NUM_SHDR_ENTRIES to size\n\tplt relocs.\n\t* elf32-arm.c (elf32_arm_get_synthetic_symtab): Likewise.\n\t* elf32-ppc.c (ppc_elf_get_synthetic_symtab): Likewise.\n\t* elf64-ppc.c (ppc64_elf_get_synthetic_symtab): Likewise.\n\t* elfxx-mips.c (_bfd_mips_elf_get_synthetic_symtab): Likewise.\n",
