binutils: Fix CVE-2017-6965 and CVE-2017-6966
Backport upstream commit to address vulnerabilities:
CVE: CVE-2017-6965
[BZ 21137] -- https://sourceware.org/bugzilla/show_bug.cgi?id=21137
Fix readelf writing to illegal addresses whilst processing corrupt input
files containing symbol-difference relocations.
PR binutils/21137
* readelf.c (target_specific_reloc_handling): Add end parameter.
Check for buffer overflow before writing relocated values.
(apply_relocations): Pass end to target_specific_reloc_handling.
CVE: CVE-2017-6966
[BZ 21139] -- https://sourceware.org/bugzilla/show_bug.cgi?id=21139
Fix read-after-free error in readelf when processing multiple, relocated
sections in an MSP430 binary.
PR binutils/21139
* readelf.c (target_specific_reloc_handling): Add num_syms
parameter. Check for symbol table overflow before accessing
symbol value. If reloc pointer is NULL, discard all saved state.
(apply_relocations): Pass num_syms to target_specific_reloc_handling.
Call target_specific_reloc_handling with a NULL reloc pointer
after processing all of the relocs.
