Backport four upstream fixes for binutils 2.42:
- CVE-2025-1147: nm segfault with --ifunc-chars=-- (PR 32556)
- CVE-2025-8224: abort in _bfd_doprnt due to shstrtabsize overflow (PR 32109)
- CVE-2026-15003: buffer overflow in xcoff_link_add_symbols (PR 34053)
- CVE-2026-18220: buffer overflow in elf32_dlx_relocate26
CVE-2025-8224 is adapted for 2.42 (uses _bfd_alloc_and_read instead of
_bfd_mmap_readonly_persistent). All other patches apply cleanly.

+Subject: [PATCH] nm: fix treating an ifunc symbol as a stab if
+ '--ifunc-chars=--' is given
+
+If an ifunc symbol is processed in print_symbol(), a 'type' field of a
+'syminfo' structure is set to any character specified by a user with an
+'--ifunc-chars' option. But afterwards the 'type' field is used to
+check whether a symbol is a stab in print_symbol_info_{bsd,sysv}()
+functions in order to print additional stab related data. If the 'type'
+field equals '-', a symbol is treated as a stab. If '--ifunc-chars=--'
+is given, all ifunc symbols will be treated as stab symbols and
+uninitialized stab related fields of the 'syminfo' structure will be
+printed which can lead to segmentation fault.
+
+To fix this, check if a symbol is a stab before override the 'type'
+field. Also, add a test case for this fix.
+
+ PR binutils/32556

+Subject: [PATCH] PR32109, aborting at bfd/bfd.c:1236 in int _bfd_doprnt
+
+Since bfd_section for .strtab isn't set, print the section index
+instead. Also, don't return NULL on this error as that results in
+multiple mmap/read of the string table. (We could return NULL if we
+arranged to set sh_size zero first, but just what we do with fuzzed
+object files is of no concern, and terminating the table might make a
+faulty object file usable.)
+
+ PR 32109
+ * elf.c (bfd_elf_get_str_section): Remove outdated comment, and
+ tweak shstrtabsize test to suit. Don't use string tab bfd_section
+ in error message, use index instead. Don't return NULL on
+ unterminated string section, terminate it.
+ (_bfd_elf_get_dynamic_symbols): Similarly terminate string table
+ section.
+
+[Backport note: Adapted for binutils 2.42. The upstream commit targets
+a newer codebase that uses _bfd_mmap_readonly_persistent and has an
+explicit unterminated-string error path with return NULL. In 2.42 the
+code uses _bfd_alloc_and_read with shstrtabsize+1 allocation and
+unconditionally null-terminates via shstrtab[shstrtabsize] = '\0'.
+Only the shstrtabsize overflow check fix applies here (shstrtabsize + 1 <= 1
+changed to shstrtabsize == 0). The second upstream hunk (DT_STRTAB
+error_return -> terminate) does not apply as 2.42 already
+unconditionally null-terminates the dynamic string table.]

Backport four upstream fixes for binutils 2.42:
- CVE-2025-1147: nm segfault with --ifunc-chars=-- (PR 32556)
- CVE-2025-8224: abort in _bfd_doprnt due to shstrtabsize overflow (PR 32109)
- CVE-2026-15003: buffer overflow in xcoff_link_add_symbols (PR 34053)
- CVE-2026-18220: buffer overflow in elf32_dlx_relocate26
CVE-2025-8224 is adapted for 2.42 (uses _bfd_alloc_and_read instead of
_bfd_mmap_readonly_persistent). All other patches apply cleanly.
Changes v1 -> v2:
- Fixed Upstream-Status placement to be in commit message (before scissors line)

+Subject: [PATCH] nm: fix treating an ifunc symbol as a stab if
+ '--ifunc-chars=--' is given
+
+If an ifunc symbol is processed in print_symbol(), a 'type' field of a
+'syminfo' structure is set to any character specified by a user with an
+'--ifunc-chars' option. But afterwards the 'type' field is used to
+check whether a symbol is a stab in print_symbol_info_{bsd,sysv}()
+functions in order to print additional stab related data. If the 'type'
+field equals '-', a symbol is treated as a stab. If '--ifunc-chars=--'
+is given, all ifunc symbols will be treated as stab symbols and
+uninitialized stab related fields of the 'syminfo' structure will be
+printed which can lead to segmentation fault.
+
+To fix this, check if a symbol is a stab before override the 'type'
+field. Also, add a test case for this fix.
+
+ PR binutils/32556
+ * nm.c (extended_symbol_info): Add is_stab.
+ (print_symbol): Check if a symbol is a stab.
+ (print_symbol_info_bsd): Use info->is_stab.
+ (print_symbol_info_sysv): Use info->is_stab.
+ * testsuite/binutils-all/nm.exp: Test nm --ifunc-chars=--.

+Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=32556

+Subject: [PATCH] PR32109, aborting at bfd/bfd.c:1236 in int _bfd_doprnt
+
+Since bfd_section for .strtab isn't set, print the section index
+instead. Also, don't return NULL on this error as that results in
+multiple mmap/read of the string table. (We could return NULL if we
+arranged to set sh_size zero first, but just what we do with fuzzed
+object files is of no concern, and terminating the table might make a
+faulty object file usable.)
+
+ PR 32109
+ * elf.c (bfd_elf_get_str_section): Remove outdated comment, and
+ tweak shstrtabsize test to suit. Don't use string tab bfd_section
+ in error message, use index instead. Don't return NULL on
+ unterminated string section, terminate it.
+ (_bfd_elf_get_dynamic_symbols): Similarly terminate string table
+ section.
+
+[Backport note: Adapted for binutils 2.42. The upstream commit targets
+a newer codebase that uses _bfd_mmap_readonly_persistent and has an
+explicit unterminated-string error path with return NULL. In 2.42 the
+code uses _bfd_alloc_and_read with shstrtabsize+1 allocation and
+unconditionally null-terminates via shstrtab[shstrtabsize] = '\0'.
+Only the shstrtabsize overflow check fix applies here (shstrtabsize + 1 <= 1
+changed to shstrtabsize == 0). The second upstream hunk (DT_STRTAB
+error_return -> terminate) does not apply as 2.42 already
+unconditionally null-terminates the dynamic string table.]
