https://sourceware.org/bugzilla/show_bug.cgi?id=22788 --- Comment #7 from Nick Clifton --- Hi JayZhang, >Can we close the issue now and make it public? Already done. :-) The fix is available in the binutils development sources and on the 2.30 branch. It will be in the next official release (either 2.30.1 or 2.31) whenever that happens.

https://sourceware.org/bugzilla/show_bug.cgi?id=22788 Nick Clifton changed: What|Removed |Added Status|UNCONFIRMED |RESOLVED Resolution|--- |FIXED --- Comment #4 from Nick Clifton --- Hi JayZhang, Exactly right. The ELF note parsing code was not expecting such a large alignment, and that caused it to attempt to read beyond the end of the buffer containing the note. I have checked in the patch, so the problem should now be fixed.

https://sourceware.org/bugzilla/show_bug.cgi?id=22788 --- Comment #2 from JayZhang --- Hi Nick, The patch you provided fixed the problem. Good job! I tried to read the code of elf_parse_notes(),and analyze the crafted file's structure,and found that the value of sh_addralign is 2^28;So,Is that the invalid sh_addralign value leads to a out of bounds reading?

I am unable to reproduce the actual failure, but I think that this is because I cannot build a 32-bit toolchain with address sanitization enabled. (This is a failure with my build environment not the binutils). In the meantime though, please could you try out the uploaded patch and let me know if it fixes the problem. Thanks.
