binutils: CVE-2017-15938
Source: binutils-gdb.git
MR: 76766
Type: Security Fix
Disposition: Backport from binutils master
ChangeID: f080669b4e6f7c9088e30858238da5f4315192f3
Description:
PR22209, invalid memory read in find_abstract_instance_name
This patch adds bounds checking for DW_FORM_ref_addr die refs, and
calculates them relative to the first .debug_info section. See the
big comment for why calculating relative to the current .debug_info
section was wrong for relocatable object files.
PR 22209
* dwarf2.c (struct comp_unit): Delete sec_info_ptr field.
(find_abstract_instance_name): Calculate DW_FORM_ref_addr relative
to stash->info_ptr_memory, and check die_ref is within that memory.
Set info_ptr_end correctly when another CU is refd. Check die_ref
for DW_FORM_ref4 etc. is within CU.
Affects: <= 2.29
